Getting ready for your next adventure abroad? You'll want to get the best eSIM for international travel before you start packing your luggage. They're a great way to make sure you're always connected wherever you are in the world, whether you're going on holiday to Asia or taking a short business trip to Europe.
We've tested the best options for reliable coverage, easy set-up, and costs, and Ubigi is the one that really stands out to me. Connection speeds are fast, pricing is competitive, and I love that there's a massive range of plans available for every type of traveler.
In testing each of the best eSIMs in this round-up, I've looked specifically at three primary areas that I think every traveler and holiday-maker worries about: speed, coverage, and cost. Here, you'll find my favorite providers for short stays, unlimited data plans, and all-inclusive services for data, text, and calls.
Best overall
✅ You travel through many different countries: Ubigi delivers dependable data in 201 countries and territories, leveraging the Transatel (NTT) global network for strong connections in most travel destinations.
✅ Finding Wi-Fi for top-ups annoys you: The Ubigi app remains accessible for plan management and top-ups even when your data runs out, so you're never stranded or forced to find Wi-Fi just to get back online.
✅ You only start your plan upon arrival: With Ubigi's Smart Start feature, your plan validity begins upon your first connection abroad, ensuring you get the full value for your travel dates.
❌ Cost is your only deciding factor.: Nomad can undercut Ubigi’s prices in some regions, so if cost is your only concern, it's worth checking Nomad’s rates for your destination before deciding.
Ubigi stands out among eSIM providers for travelers by offering access to mobile data in 201 countries and territories, all through its status as an MVNO on the Transatel global network. In our testing, this meant consistently reliable connections and fast speeds in places as varied as Western Europe, Asia, and the US. That breadth of coverage gives Ubigi an edge for anyone seeking dependable international connectivity across multiple regions in a single trip.
One practical advantage we appreciated was how the Ubigi app remains accessible for top-ups or plan management even when your data balance hits zero, so you’re never stranded without a way to reconnect. The Smart Start feature is another thoughtful touch: plan validity only begins when you first land and connect in your destination, so you get the full value of your purchase rather than losing days to airport layovers or pre-trip prep.
On a recent trip, our lead tester installed Ubigi’s eSIM before flying, set up the account at home, and then simply activated a new data plan each time they landed in a new country. There was no need to scan a QR code or reinstall the eSIM between trips—just tap to add a plan and go. For frequent travelers who want to minimize setup hassles, that kind of reusability is a real timesaver.
Ubigi offers a choice of one-off, monthly, and annual plans, so you can select exactly what fits your itinerary, whether it’s a quick weekend away, a multi-country month-long journey, or an entire year abroad. We found the plan options clear and flexible, with upfront pricing for local, regional, and global coverage.
When compared to Nomad, Ubigi’s prices aren’t always the lowest. Nomad can beat Ubigi in certain countries. And while Airalo matches Ubigi for global reach, it lacks the zero-rated top-up feature and Smart Start activation, which make Ubigi easier to use on the go. If you value pure price over usability, you might want to check Nomad’s rates for your specific destination.
Against Airhub, Ubigi leads on network reliability and app convenience, especially for straightforward data needs in many countries, but Airhub offers extras like security features and multi-network support that Ubigi doesn’t include. If you’re seeking bundled security or voice/SMS add-ons, Ubigi may not be your pick. For most travelers, though, its simple app and broad coverage win out.
Ubigi’s customer support isn’t as fast or hands-on as some rivals. Live chat is limited and responses can be slow, so it may not be ideal if you need immediate help mid-trip. If your top priorities are global reach, easy in-app management, and plans that adapt to a variety of travel styles, Ubigi is a dependable choice for both frequent and occasional travelers who want less hassle and more coverage.

Best for security
✅ Direct privacy control is your priority: Saily’s integrated ad blocker, web protection, and virtual location tools put end-to-end security at the heart of every connection, giving you direct control over your privacy while traveling.
✅ You're a security-conscious traveler: As part of the Nord Security ecosystem, Saily is designed from the ground up to protect your data abroad—ideal for security-conscious travelers.
✅ Delayed technical help worries you: Saily’s 24/7 live chat inside the app means you’re never left waiting for help with eSIM setup or account recovery, reducing potential security risks on the road.
❌ You expect perfectly uniform connection speeds: In regions like Vietnam, our team found Saily’s coverage and speeds less reliable. If connection quality is your top concern, double-check local network partners before purchase.
❌ Offline activation is a must for you: Saily requires a Wi-Fi connection for initial eSIM activation, so if you need a service that works instantly upon arrival without Wi-Fi, this could be a limitation.
Saily stands out as a rare eSIM service built explicitly for travelers who prioritize online security, drawing on the Nord Security pedigree. What sets it apart is the built-in suite of protections, including an ad blocker, web protection, and a virtual location feature, all embedded into the Saily app for a seamless, privacy-first experience.
Saily’s security tools aren’t just for show. The ad blocker and web protection directly filter out trackers and malicious sites before they reach your device, while the virtual location option lets you mask your whereabouts when browsing abroad. For anyone worried about third-party tracking or data interception on unfamiliar networks, these features offer real, on-device defenses with every connection.
Our team verified that Saily’s eSIM coverage extends to over 200 countries and territories, so you get the same core privacy tools nearly everywhere you travel. In practice, this lets you maintain a single, consistent security posture from country to country, something most eSIM rivals can’t match.
Provisioning is straightforward. After purchasing, your eSIM profile is securely delivered and activates automatically when you arrive at your destination. You’ll need a Wi-Fi connection for initial activation, but once set up, Saily handles the rest in the background. This automatic approach reduces the risk of accidental misconfiguration, a crucial detail for anyone concerned about setup vulnerabilities.
If you ever run into trouble, Saily’s in-app live chat support is staffed 24/7. Our team found this especially valuable for rapid account recovery or if your eSIM profile needs resetting while traveling. Speedy, knowledgeable responses help resolve issues before they become security risks.
Where competitors like Ubigi and Airalo may offer unlimited data or even broader destination lists, Saily’s biggest differentiator is its robust security suite. While AloSIM, Airhub, and Nomad compete on price or data options, none match Saily’s integrated protections. If your priority is safeguarding your connection and personal data while abroad, these features tip the balance in Saily’s favor.
Real-world performance isn’t uniform everywhere. During our testing, Saily worked seamlessly in Thailand (using the local True network), but we hit connectivity snags in Vietnam, where networks didn’t always deliver reliable speeds. Security is only as useful as your connection, so we recommend checking Saily’s local network partners before you buy for each trip.

Best for global plans
✅ You're visiting several countries this trip: Airalo offers prepaid data plans in more than 200 countries and regions, making it a standout for travelers needing broad and dependable coverage.
✅ Border-crossing signal drops frustrate you: With local, regional, and global plan tiers, Airalo lets you tailor coverage to your trip route, with clear territory lists for each option.
✅ Your itinerary spans many different regions: Airalo supports hotspot/tethering, so you can connect your laptop or tablet on the go as well as your phone.
❌ Your trip includes flights or cruises: Airalo doesn't offer inflight or cruise ship data plans, so if your trip includes these segments, you'll want a more specialized provider.
Airalo stands out for travelers who need reliable mobile data in over 200 countries, offering broad coverage and a strong track record for consistent connectivity. In our experience, its service consistently just works across borders, making it a dependable pick for anyone moving between multiple regions.
Plan structure is straightforward: you choose from local, regional, or global eSIMs, each with clearly listed coverage territories. This tiered approach lets you tailor your plan to specific itineraries, which is ideal if your trip spans several countries or you want the flexibility to top up only where needed.
All Airalo plans are data-only, so you won’t get phone calls or SMS, but you can select between fixed-allowance or unlimited data options. Unlimited plans operate under a fair usage policy, and once you hit the threshold, speeds are throttled. Tethering is supported, so you can hotspot from your phone to a laptop or tablet, covering more of your connectivity needs abroad.
Usability is another strong point. The Airalo app supports 53 languages, and help is available 24/7 via in-app chat or WhatsApp in multiple languages. There’s no option for phone-based support, so plan on resolving issues through digital channels.
In real-world travel, we found Airalo’s speeds were reliably sufficient for maps, messaging, and light browsing, aligning with what most travelers actually use on the move. It's not always the fastest, but typical tasks work smoothly on most networks.
Airalo’s pricing is competitive, though not always the lowest. Nomad sometimes edges it on cost. Unlimited data is available, but for truly unlimited plans, Holafly is more focused in that niche. If you need local calls and SMS, Airhub offers those features, which Airalo does not. These trade-offs are worth weighing based on your own trip priorities.
For most international travelers, Airalo is a pragmatic choice: broad coverage, flexible plans, and reliable connections. It’s not the best fit if you need inflight or cruise connectivity, local phone numbers or SMS, or the absolute lowest price with speed-capped or free data. For most global trips, it covers the essentials without fuss.

Best for easy installation
✅ One-tap activation is your top priority: aloSIM’s app walks you through setup with tailored instructions for your device, making it easy even if you’ve never used an eSIM before.
✅ A Real phone number: aloSIM includes a real phone number on certain plans, so you can make calls, receive SMS codes, and stay reachable—especially useful when traveling abroad.
❌ 5G speeds or unlimited data matter to you: aloSIM doesn’t offer any unlimited data or 5G plans, so it’s not the best pick if you expect heavy usage or want the fastest possible mobile speeds.
❌ You expect the broadest coverage or loyalty perks: aloSIM’s coverage is more limited than Nomad, and you won’t find a loyalty program like you get with Airalo.
❌ Broadest coverage or loyalty perks are your priority: For high-volume users or those wanting more plan variety, Saily, Airhub, or Airalo typically offer better pricing and a wider range of options.
aloSIM stands out for its automatic eSIM installation, making it the simplest service we’ve tested for getting mobile data on your phone before you travel. The process is refreshingly beginner-friendly: just pick a plan, tap a button, and aloSIM does the heavy lifting. No technical know-how required. Installation is truly one-step, with the eSIM staying on your device for the duration of your trip, so you don’t have to worry about redoing it mid-journey.
If you’re worried about device compatibility or feeling out of your depth with eSIM technology, aloSIM’s step-by-step setup guide is a genuine safety net. The app identifies your device and walks you through each stage, including fallback options for manual installation and a QR code scan that works with almost every phone. The clear, device-specific instructions cut out most of the confusion that trips up first-time users.
A standout feature: select aloSIM plans bundle a local phone number through Hushed. For travelers, this is a lifesaver. Our tester once found herself unable to receive SMS verifications or calls when using a data-only eSIM abroad. Having a real number means you can handle two-factor authentication, call taxis, or book reservations without juggling extra apps or worrying about being unreachable.
aloSIM supports hotspot sharing at no extra cost, which is ideal if you need to connect a laptop or help travel companions get online. That flexibility is rare, with some eSIM services locking hotspot use behind premium plans or higher fees.
Compared to other major eSIM providers, aloSIM’s automatic installation is a key differentiator. Services like Ubigi and Saily also offer QR-based or app-guided installs, but most require more manual steps or lack a robust fallback guide if things go wrong. The bundled phone number on certain aloSIM plans is still rare. Airalo, Airhub, and Nomad typically only provide data. However, aloSIM falls behind on plan variety, coverage breadth, and loyalty perks. It lacks unlimited data, global roaming is more limited than with Nomad, and frequent travelers may find better deals or broader networks elsewhere.
You won’t find unlimited data or 5G plans here, and coverage can be patchy in less-traveled regions. Plan selection is narrower than some competitors, and prices aren’t always the lowest for high-volume users. Check network compatibility in your destination before relying on aloSIM as your only option.
aloSIM is best for travelers who want a straightforward, stress-free setup and value having a real phone number while abroad. If you want the lowest rates, 5G, or global coverage, you’ll need to look elsewhere. For fuss-free installation and practical features, it’s an excellent pick. The full review breaks down plan options and direct comparisons in more detail.

Best for network coverage
✅ You travel across many continents: With a presence in more than 190 countries and territories, Airhub stands out for travelers who value connectivity across multiple regions or continents.
✅ Wide coverage is your top priority: Airhub's broad selection of local, regional, and global eSIM plans makes it easy to adapt your coverage to your trip, whether you're hopping cities or planning a multi-country tour.
✅ If you're visiting multiple countries: Many Airhub plans include an international phone number, so you can send texts or make calls in addition to using data—ideal for staying in touch while traveling.
❌ Universal 5G coverage is a must for you: Airhub mainly provides 4G LTE speeds, with 5G only available in certain locations. If fast 5G connections are essential for you, another provider may suit you better.
❌ You need ease of use: In our tests, Airhub's activation process was less streamlined than some competitors, and response times from customer support were slower than ideal.
Airhub stands out with a coverage footprint that spans more than 190 countries and a deep catalog of local, regional, and global eSIM plans. If you prioritize staying connected across borders, Airhub’s extensive coverage and variety of options are reassuring.
In our hands-on experience, Airhub maintained steady connectivity throughout Europe and Asia, with no dropped connections, and topping up mid-trip was fast and glitch-free through the app. This reliability offers peace of mind when traveling. Airhub connects through a range of local carrier partners in each country, so you can often switch networks for the best available signal.
A key differentiator is that many Airhub plans come with an international phone number, making it possible to place and receive calls or texts as you travel. This feature offers an extra layer of flexibility.
Stacked up against Airalo and Saily, Airhub covers more countries and offers a wider selection of regional plans. Airalo edges it out for pure global plan customization, and Saily has a slight advantage in security features, but if your itinerary hops across multiple regions, Airhub’s sheer variety is hard to beat.
On the speed front, Airhub’s data plans are mainly 4G LTE, with some 5G available in select countries. While 5G availability is limited, the 4G LTE coverage generally meets the connectivity needs of many travelers.
The main weaknesses: activation can feel clunky compared to the slickest competitors, and coverage in parts of Latin America proved patchy in our tests. If you want maximum coverage, Airhub is a practical pick for itinerary-driven travelers who can overlook a few rough edges.

Best value for money
✅ High roaming fees frustrate you: Nomad’s European plans start at just $0.66 per GB, undercutting domestic roaming charges and most rivals, giving you clear cost control.
✅ You're hunting for the best per-GB price: If you travel often or for longer periods, the Nomad Pass subscription lets you pay monthly for data in key regions, offering extra savings and flexibility.
✅ You travel frequently for long periods: Setting up Nomad’s eSIM took us less than five minutes and the process worked smoothly on both Android and iOS—install before you travel for instant arrival connectivity.
❌ You require unlimited data or roaming: Nomad doesn’t offer unlimited data plans or true worldwide coverage; if your trip requires these, options like Airalo or Saily may suit you better.
❌ Unlimited data or roaming matters to you: Nomad has fewer plan choices per country, especially outside Europe, so if you value a wide array of options for each destination, look to Airalo or AloSIM.
❌ You expect many options per destination: Nomad’s 4G/5G access depends on local networks, so speeds can vary; this could be a drawback if you need guaranteed performance everywhere.
Nomad eSIM stands out for travelers seeking to minimize data costs, with European plans starting at just $0.66 per GB, well below what most domestic carriers charge for roaming. This pricing makes Nomad eSIM a strong option if you're focused on value, especially when compared to traditional roaming services.
For longer trips or regular travel, the Nomad Pass subscription option provides practical flexibility. You pay monthly for data in select regions, with a base of 1 GB of Europe regional data for $3/month and a 15% discount on add-ons. This approach gives buyers more ways to tailor their spend, without getting locked into rigid contracts.
Nomad eSIM supports 4G and 5G connections in key destinations, so you can expect solid speeds in most tourist and business hubs. Your actual experience will depend on the local partner networks, and connection speeds can vary based on location.
Setup is refreshingly simple. Installing and activating a Nomad eSIM through the app took just minutes, with the process feeling intuitive even for first-timers. Our lead tester recommends installing before you depart to guarantee connectivity as soon as you land—a small step that makes a big difference if you need to be online immediately.
Compared to rivals like Ubigi, Saily, Airalo, AloSIM, and Airhub, Nomad eSIM generally offers competitive pricing for Europe and major regional plans. If you need unlimited data, sprawling global coverage, or extras like voice/SMS options, some competitors may be a better fit. For straightforward regional data, Nomad eSIM remains a solid choice.
There are a few trade-offs to note. Nomad eSIM doesn't offer unlimited data plans or the broadest country coverage, and in some regions, there are fewer plan options per country than you'll find with Airalo or AloSIM. If your itinerary includes less common destinations or you want maximum plan flexibility, consider these factors.
Nomad eSIM is a great choice if you want low-cost data for Europe or other popular regions, appreciate a quick setup, and can select your plan before you travel. For the most features or worldwide coverage, you may want to look at competitors. Check our full review for in-depth plan breakdowns and country specifics.

Best for inflight data plans
✅ You're flying for just one day: FlexiRoam's dedicated 24-hour inflight plans with upfront pricing make it ideal if you need data during a single flight or for a layover, without committing to a long-term package.
❌ You stick to a strict budget: FlexiRoam's inflight plans are significantly more expensive than general-purpose eSIM services, so travelers on a tight budget will find better value elsewhere.
FlexiRoam stands out for travelers needing predictable inflight connectivity, offering dedicated 24-hour inflight data plans with transparent, upfront pricing. If you want to avoid surprises on your next long-haul flight, knowing exactly what you'll pay for a short burst of data makes this service immediately appealing.
Its coverage extends to over 200 countries and regions, and FlexiRoam's automatic switching between local carriers is especially useful for keeping a connection not just in the air, but in airports and across borders. This multi-network support addresses one of the main pain points of global travel: inconsistent service when moving between regions.
Compared to more general eSIM providers like Ubigi and Nomad, FlexiRoam is unique in offering explicit inflight plans geared to those needing data above the clouds. However, you will pay a premium for this. Both Ubigi and Nomad offer broader, often less expensive plans, particularly for unlimited or 5G data. FlexiRoam's inflight plans are a niche solution and are priced accordingly.
That price stands out as the main drawback. If you're on a tight budget or need value-focused service for extended travel, FlexiRoam's rates can be hard to justify, especially when measured against more cost-effective competitors.
FlexiRoam is best suited to travelers who prioritize inflight or very short-term data needs and want the certainty of clear, short-duration pricing. If your priority is maximizing data for the lowest price, or accumulating loyalty rewards, global plans from Airalo and others may be a better fit.

Best for cruises
✅ You're heading on a cruise soon: GigSky’s dedicated cruise and in-flight plans, plus automatic network switching, make it easy to stay online both at sea and in port.
✅ Technical setups usually frustrate you: Getting GigSky onto your phone takes about five minutes, and there is nothing technically demanding about it as long as you do it before you leave.
✅ Hidden fees and gaps annoy you: GigSky’s cruise packages are easy to select, clearly described in the app, and avoid the patchwork coverage of some competitors.
❌ Unlimited cruise data is a priority: While Holafly offers unlimited data on some routes, GigSky’s cruise plans have data limits.
❌ You only need basic land-based coverage: GigSky’s cruise plans may cost more than basic land-only packages from providers like Airalo.
❌ Pre-departure setup doesn't work for you: For the smoothest experience, GigSky’s eSIM should be installed before you leave, which may not suit last-minute planners.
GigSky stands out as the best eSIM for cruises, thanks to its dedicated cruise plans and seamless network switching that make staying connected at sea straightforward. The service covers over 200 destinations, but what sets it apart for cruise travelers is the inclusion of cruise-specific and in-flight data packages, something not all competitors offer.
We found GigSky’s cruise plans easy to select and clearly described in the app, with options tailored for major cruise lines and popular itineraries. Unlike Airalo, which focuses more on land-based regional packages, GigSky’s cruise coverage is designed to keep you online even when you’re far from shore. This dedicated approach means you can rely on your connection for messaging, maps, or last-minute bookings while at sea.
A highlight of our experience was GigSky’s automatic network switching. When the ship docked at a new port, the eSIM transitioned smoothly from maritime to local terrestrial networks without any manual intervention. This feature removes a common frustration for cruise travelers and ensures you’re not left scrambling for connectivity as you move between countries and open water.
Getting GigSky onto your phone takes about five minutes, and there is nothing technically demanding about it as long as you do it before you leave. Our lead tester found the installation process intuitive: scan the QR code, follow the prompts, and you’re set. Install the eSIM before your travels, then activate it once you have landed. This pre-trip setup gave us peace of mind, knowing we’d have instant access to data once onboard.
Compared to competitors like Airalo and Holafly, GigSky’s cruise plans are more specialized. While Holafly offers unlimited data on some routes, GigSky’s clear pricing and reliable switching between cruise and land networks make it a safer bet for most cruise itineraries. There are no hidden fees or complicated top-ups, just straightforward packages for the duration of your trip.
If you want hassle-free connectivity on your next cruise, GigSky’s dedicated plans and smooth activation process make it a reassuring choice. It’s especially useful if you value automatic network switching and want to avoid the uncertainty of patchwork coverage at sea. For cruise travelers who prioritize reliability and simplicity, GigSky is our top recommendation.

Best for frequent travellers
✅ You often face flight delays: Jetpac’s SmartDelay feature gives you free airport lounge access if your flight is delayed—a perk that can make a huge difference for frequent flyers dealing with travel disruptions.
✅ You're testing coverage before committing: Jetpac’s $1 trial lets you check coverage and speeds on your device before you commit, so you know exactly what to expect on your trip.
✅ Fast support is your priority: We received replies from Jetpac’s support team within minutes via live chat and email, making it a reliable option if you need help while traveling.
❌ Truly unlimited data is your priority: Jetpac throttles unlimited plan speeds after 3GB per day, so if you stream or tether extensively, this may not meet your needs.
❌ Your itinerary spans over 150 countries: Jetpac covers 96 countries, which is fewer than some competitors. If you have complex itineraries touching more regions, consider eSIMs with broader coverage.
❌ You expect automated setup on Android: Android users may need to manually set the APN before connecting with Jetpac. If you prefer absolute simplicity, this extra step could be a dealbreaker.
Jetpac stands out among travel eSIMs with its SmartDelay benefit, offering free airport lounge access if your flight is delayed. For frequent flyers, this adds genuine value on unpredictable travel days by providing a comfortable place to wait during disruptions.
As a travel companion, Jetpac covers 96 countries and lets you buy one-time data packs without any subscription commitment. You can pick up coverage for your exact itinerary and avoid ongoing charges between trips, a flexibility that's ideal if you bounce between regions or only travel a few times a year. The main limitation is that its country list, while broad, isn’t as universal as some rivals with 150+ options.
If you’re wary of potential connectivity issues or just want to see how Jetpac performs on your route, there's a $1 trial available. We found this trial setup to be an easy, low-stakes way to confirm that coverage and speeds work where you need them, especially helpful for travelers who want to avoid surprises on arrival.
Setup is straightforward. Our lead tester installed Jetpac before heading to the airport and was online in under two minutes after landing. For most users, it’s nearly instant, although some Android devices may require a quick APN adjustment. This no-fuss process makes Jetpac practical for repeat trips or last-minute getaways.
If you ever hit a snag, Jetpac’s customer support impressed us. We received prompt replies via both live chat and email, typically within minutes, an important backup when you’re on the ground in a new country and need help fast.
Jetpac’s SmartDelay lounge perk is a unique differentiator you won’t find with competitors like Ubigi, Airalo, or Airhub. Those offer wider global coverage but lack travel perks for disrupted flights. In exchange for a slightly smaller country list, you gain a comfort-focused feature that can smooth rough travel days.
Unlimited data users should note: Jetpac throttles speeds after 3GB per day, which is a real limitation if you’re streaming or tethering heavily. Still, for most business or leisure travelers, especially those flying frequently, Jetpac’s blend of flexibility, fast setup, and lounge access makes it a travel-savvy pick, provided your destinations are on its list.

Best for unlimited data
✅ Monitoring your data usage frustrates you: Holafly’s unlimited data plans are designed for heavy data users who don’t want to monitor or ration their usage abroad. In our testing, reliable 4G/5G speeds made it easy to stream, browse, and work without worrying about running out of data.
✅ You travel through multiple different countries: With unlimited plans spanning over 190 countries, Holafly is a go-to if your travels take you to multiple destinations and you want a single solution for connectivity.
✅ You're activating data right after landing: Activation took us just a few minutes using the QR code, and the app made onboarding straightforward—ideal if you want to be online immediately after landing.
❌ Constant high-speed access matters to you: Holafly may throttle your speeds after 3–5GB of daily usage, depending on the country and carrier. If constant, uninterrupted top speeds are critical, this limitation could be a dealbreaker.
❌ You tether your laptop to your phone: Holafly’s unlimited plans don’t allow hotspots or device sharing, so you can’t connect laptops or friends’ devices. That’s a limitation if you rely on sharing your connection.
❌ You want the cheapest unlimited plan: Holafly is more expensive than Airalo and Ubigi. If price is your top concern and you’re willing to track or top up data, a rival might suit you better.
Holafly stands out for its unlimited data plans that let you use your phone across 190+ countries without worrying about running out of data— but only if you don't intend to use more than a few gig a day. For frequent travelers or anyone who streams, navigates, or works remotely abroad, you might not get on with Holafly because of throttling. Instead, you should buy a large data pack and use it until it's gone and buy again. No throttling and it'll be cheaper.
While Holafly advertises unlimited data, speeds may be reduced after you use 3–5GB per day, depending on the destination and local carrier. For most travelers, this isn’t a dealbreaker, but if you expect to stream or work heavily at full speed every day, you may encounter some throttling after hitting that threshold.
Another limitation is that Holafly’s unlimited plans don’t support hotspot or device sharing, so you can’t connect your laptop or share data with travel companions. If you need to tether multiple devices, this could be a sticking point.
Holafly is typically pricier than rivals like Airalo and Ubigi, and the lack of hotspot support is a trade-off. If you value unlimited data (kind of) without worrying about top-ups or overages, the premium is easy to justify. Coverage is broad, though a few competitors reach even more destinations.
We did notice occasional connectivity gaps in remote or less-developed areas, so if your travels take you far off the beaten path, check Holafly’s coverage map before you buy. For most international travelers prioritizing data freedom and simplicity, Holafly remains a compelling pick.

Best for free speed-capped data
✅ Paying for data upfront frustrates you: Firsty's free tier gave us instant access for messaging and email as soon as we landed, with no upfront payment required.
✅ You're activating data before you fly: We installed and activated Firsty's eSIM at home, so we had working data the moment our plane touched down—no airport hassle.
✅ Connectivity upon landing is essential: The Comfort+ and First Class upgrades are just a tap away and charge only for days you use, so you can boost your speeds when needed without committing to a subscription.
❌ High-speed data is a must for you: At 128kbps, Firsty's free plan is only good for messaging and light browsing; you’ll need a paid or premium option for anything heavier.
❌ Privacy and no ads matter to you: To keep using the free plan, you'll need to watch short ads every hour and share basic device data with advertisers.
❌ Your itinerary includes Asia or the Americas: Firsty's free tier only works in 74 countries, skipping most of Asia and the Americas, so check the coverage map if your travel goes beyond Europe or the Med.
Firsty offers a genuinely free data tier that delivers real, if modest, connectivity at capped speeds. In my tests, the free plan reliably supported essential tasks like messaging and email, which is exactly what budget-conscious travelers or those with light data needs are after.
Firsty's free data is available in 74 countries, covering much of Europe and many major tourist destinations, but skipping large regions in Asia and the Americas. If your trip is off the beaten path, double-check the coverage map before relying on the free plan.
Getting started was refreshingly straightforward. I installed Firsty's eSIM before leaving home and activated it instantly upon landing. There were no hoops to jump through or confusing menus, a clear win for anyone who wants to avoid airport SIM counters or fiddly QR codes.
The trade-off for free data is that Firsty operates on an ad-supported model: after your first 59 minutes, you'll need to watch a short ad to unlock another hour of connectivity. This won't suit anyone wary of sharing basic device data with advertisers, and Saily offers a paid-only, ad-free experience for privacy-focused users.
If you need more than basic connectivity, upgrading is painless. For €1 a day, Comfort+ unlocks much faster speeds and removes ads. For €2 a day, First Class delivers full-speed data with hotspot support. The process is pay-as-you-go, no subscriptions, no commitment, and you only pay for days you use.
Stacked against Nomad, Ubigi, and Airalo, Firsty wins on cost for light users but can't match their broader coverage footprints or always-on high-speed access. Nomad and Ubigi both support more countries, while Airalo is better suited to longer or multi-country trips where reliable fast data matters more than price alone.
If your goal is to stay connected for maps, messages, and email without spending a cent, Firsty is hard to beat. Just be realistic: it's not built for streaming or heavy browsing, and frequent travelers heading outside Western Europe or the Mediterranean will hit its coverage limits quickly.

Best for 5G performance
✅ You stick to major metropolitan areas: ByteSIM offers 5G connectivity where local infrastructure supports it, ensuring high-speed data in urban areas.
✅ You're tethering a laptop or tablet: Most ByteSIM plans allow unlimited hotspot sharing, making it ideal for connecting laptops, tablets, or travel companions without restrictions.
✅ China's internet restrictions frustrate you: ByteSIM provides dependable coverage in mainland China, including access to Google and WhatsApp without a VPN.
❌ Universal global coverage is essential for you: ByteSIM’s regional plans cover fewer countries than some competitors, and most plans do not include a phone number or SMS functionality.
❌ Your usage requires frequent data refills: Topping up with ByteSIM requires purchasing a new plan outright, and data may be throttled after hitting a daily cap.
❌ Native security features matter to you: Unlike Saily, ByteSIM does not offer built-in VPN or additional privacy extras.
ByteSIM stands out for travelers seeking high-speed data connectivity, offering 5G service wherever local infrastructure supports it and falling back to 4G/LTE as needed. In my experience, ByteSIM delivered 5G performance in major cities, and speeds were sufficient for typical travel needs, though I did not specifically test video calls, streaming, or upload performance. Coverage is broad, with eSIM service available in over 200 regions and regional plans spanning more than 125 countries.
What distinguishes ByteSIM from many rivals is its unlimited hotspot sharing on most plans. Unlike providers that restrict tethering, ByteSIM imposes no such limits, making it a strong option for users who need to connect laptops, tablets, or travel companions. If you’re heading to China, ByteSIM is especially notable: it provides reliable coverage in mainland China, including access to Google and WhatsApp without a VPN, which can be essential for staying connected in restricted environments.
Compared to competitors, ByteSIM’s coverage is slightly narrower than Ubigi’s, but it prioritizes 5G speed and hotspot flexibility. Against Saily, ByteSIM offers faster network speeds but doesn’t include built-in VPN or enhanced privacy features. It’s also more competitive than Airalo for regional plans and hotspot support, making it a better fit for multi-device users.
I activated ByteSIM in minutes before a flight to Asia and used it as the sole data source across airports, hotels, and trains in Japan and South Korea. Hotspot sharing worked flawlessly with multiple devices, and the 5G connection stayed stable in all tested environments, from city centers to rural stops.
There are some trade-offs. ByteSIM’s regional plans don’t match the absolute global reach of some competitors, and most plans are data-only without phone numbers or SMS. Data can be throttled if you hit a daily cap, and topping up requires purchasing a new plan rather than simply adding data. If you need reliable, high-speed data for multiple devices and are comfortable checking plan details before your trip, ByteSIM’s combination of 5G connectivity, broad coverage, and flexible hotspot sharing makes it a compelling travel eSIM option.

Best eSIMs for international travel FAQs
What is an eSIM?
eSIMs are digital SIM cards already embedded in your mobile device. They are small rewritable chips fixed inside your phone, which connect with an antenna to eliminate the need for a physical SIM.
Since an eSIM is rewritable, you can change your operator with just a simple setting change. The antenna connects to whichever network you select, so there’s no need to purchase a new SIM.
eSIMs have been around for quite some time. But when Apple decided to remove the good old SIM card slot and shift the iPhone to being completely eSIM-featured, this feature got its moment in the spotlight. The main reason eSIMs are preferred is because of their ease of use.
Some other reasons why eSIMs have gained popularity include environmental sustainability, reduced battery consumption, and the ability to switch networks on the fly in remote areas.
While there’s no major difference between using an eSIM card and a physical SIM card, eSIMs could be a slight turnoff when you want to switch phones. That said, the benefits of eSIM certainly outweigh physical SIM cards in most scenarios.
Why should I get an eSIM for international travel?
The best thing about an eSIM is that you can store as many as eight (sometimes even more) on your phone and activate them when needed without additional roaming charges.
Of course, if your current network operator provides free roaming service, there's no need to consider a travel-specific or local SIM. But if that's not the case, it can be quite a task to find the right operator and negotiate with language barriers.
eSIMs are also generally more secure than physical SIMs since there’s no way to remove them, so they can’t get lost. And if your phone gets lost or stolen, tracking it is much easier since eSIMs cannot be removed from the device.
Note that international roaming works the same way on physical SIMs and eSIMs. The only difference that sets the two apart is that while you can add only two physical SIMs at a time, you can conveniently purchase an eSIM from a local carrier and switch your eSIM operators as you visit multiple locations.
Is my phone compatible with eSIM?
Most phones manufactured after 2018 are compatible with eSIMs, except for a few exceptions depending on the location and carrier. iPhone XS, XS Max, and XR are among the first eSIM-compatible iPhones that came out in 2018.
To check if your phone supports an eSIM, follow these steps:
For iPhone
- Go to Settings > General > About
- Scroll down to find the Carrier Lock section
- If your device is unlocked, it will show "No SIM restrictions" If that's not the case, you need to unlock your device first.
- If you have an iOS 15 or later, Scroll down to "Available SIM" and if you have earlier iOS versions, find "Digital SIM"
- If your phone supports eSIMs, it will show a 15-digit IMEI number
For Android
Because different Android phones handle SIM and eSIM differently, it's best to check with the manufacturer. However, one process would be:
- Open Settings
- Select About Phone
- Look for SIM Status or a similar option
- Check for any mention of eSIM or Embedded SIM
Alternatively, go to Network & Internet in the Settings menu, and tap "eSIM cards". If you find a "Download a SIM instead?" option, your device is eSIM-compatible
You can also check if your phone has an EID (Embedded Identity Document Number), which is the serial number that matches the eSIM embedded in your device. To do this:
- Dial *#06# and press call
- If your device is eSIM-compatible, you'll be able to view your EID number
How to choose the best eSIM for international travel
While all the providers have something or the other to offer, it's important to know the factors that make an eSIM the best among them.
1. Which place are you traveling to?
It's important to check the network coverage of an eSIM in the place you're visiting. eSIM providers often offer amazing coverage in particular countries but mediocre performance in others. This is because eSIMs collaborate or partner with local service providers in different countries to enhance network coverage.
So, make sure that you check the service of the local provider that's accessible to you and select the eSIM provider that has coverage for the place you're traveling to.
Depending on the number of places you are going to visit, you can select local, regional, and global eSIMs. Here's how they differ:
- Local eSIM — You should go for this eSIM if you're traveling to just one country. For example, if you're traveling to Paris, you can get a local France eSIM.
- Regional eSIM — This is a perfect option if you're going to travel to a couple of countries within the same region. Let’s say you're planning a European trip; in that case, instead of buying a local SIM for each country, it’s a lot more convenient to get a regional eSIM that will work in all the countries in Europe you're visiting.
- Global eSIM — Global eSIM allows you to connect to several countries all over the world, which is perfect if you're going to travel worldwide or to countries that are in different regions.
2. How much data will you need?
If your data requirements are ambitious, you should preferably look for a cheap eSIM or one that provides unlimited data. On the other hand, if your data needs aren't too demanding, but you need internet in remote places, you might have to shell out a bit more for quality internet. To get an idea of how much data different apps use up, have a look at this:
- Google Maps: 5MB per hour
- Social Media: 50MB per hour
- Internet Browsing: 50MB per hour
- Online Gaming: 70+MB per hour
- Streaming Music: 100MB per hour
- SD Video: 1GB per hour
- HD Video: 4GB per hour
- 4K Video: 7GB per hour
3. How long will you be abroad?
All eSIM providers have different validity options — you can choose between 7, 10, 15, 30, 60, 90-day plans, and so on. Find a plan with a validity period that outlines how long you're going to be using the eSIM.
Some eSIM providers provide plans shorter than 7 days; look out for them if you're going to be away for the weekend. On the other hand, if your data usage is moderate, but you are traveling for longer periods, an unlimited plan might be the best for you.
Can I use more than one eSIM provider when traveling abroad?
Yes, you can use more than one eSIM, depending on whether you use Android or iOS. When traveling, you’d want to use at least two SIMs simultaneously so that you don't lose touch with the older SIM contact when using the new local SIM.
iPhones can store up to 5-10 eSIMs on the device, depending on the exact model. For example, the iPhone 13 Pro Max, iPhone 13 Pro, iPhone 13, and iPhone 13 Mini allow you to use two eSIMs simultaneously. On the flip side, you can use only one eSIM with iPhone 12 models, iPhone 11 models, iPhone XS, iPhone XS Max, and iPhone XR.
Similarly, Androids can also store 5-7 eSIMs on the device. However, you can only activate and use one eSIM at a time.
This makes your work a lot easier. Suppose you’re traveling to Asia and Europe within a short span of time; you can purchase two eSIMs on your device. Simply activate the eSIM once you transition from one destination to another. This is more convenient compared to traditional SIMs, where you would have had to physically purchase a SIM at every destination you visit.
Traditional phones generally feature a maximum of 2 SIM cards in devices with dual SIM slots. In devices like iPhones that usually don't have a dual SIM feature, you will have to get a student device if you wish to use more than one SIM at once.
Are eSIM better than physical SIM cards?
eSIMs offer several advantages over traditional SIM cards. They provide greater flexibility, convenience, and security for users, all while saving device space and reducing battery consumption.
While the technology is still relatively new and not universally supported yet, eSIMs will likely become the standard in the coming years as more devices and carriers adopt them.
Here’s an overview of some key advantages of using an eSIM:
Seamless activation
One of the biggest advantages of eSIMs is the ease of activation and switching between carriers. With an eSIM, you can activate service or change providers with just a few taps on your device, without having to go to a store to get a physical SIM.
This makes it much more convenient, especially when traveling internationally.
Increased security
eSIMs offer enhanced security compared to physical SIMs. They cannot be physically removed or stolen from a device, reducing the risk of unauthorized access or SIM cloning. Some eSIMs even have self-destructing features that erase data after failed authentication attempts
Designs options
Since eSIMs are embedded directly into devices and don't require a separate slot, they free up valuable space inside smartphones. This allows manufacturers to make devices slimmer, include larger batteries, or add other features. The lack of a removable SIM tray also improves water and dust resistance.
Multiple profiles
A single eSIM can store multiple carrier profiles, allowing you to switch between them as needed. This is especially useful if you want to use separate lines for work and personal use on a single phone, or if you frequently travel and need to use local services in different countries.
With an eSIM, you can do this without juggling multiple physical SIM cards.
Reliable connectivity
eSIMs can provide more reliable connectivity than physical SIM cards. SIM cards can come loose, get damaged, or degrade over time, potentially leading to signal issues. The embedded nature of eSIMs makes them less prone to these physical connectivity problems.
Environmental sustainability
Switching to eSIMs offers significant environmental benefits compared to using physical SIM cards. eSIMs eliminate the need for plastic SIM card production, packaging, and transportation, reducing the telecom industry's carbon footprint.
By enabling remote provisioning and digital distribution of SIM profiles, eSIMs also cut down on the need for users to travel to stores for activation or changes, further decreasing emissions.
Are there any risks to using eSIMs?
eSIMs are no more dangerous than physical SIM cards. They both employ the same encryption methods and security protocols to protect user data.
The only possible security disadvantage of eSIMs is that they are a relatively new technology, and some users may find the setup process more complex.
But, in many cases, eSIMs may actually be safer. Unlike physical SIMs, eSIMs cannot be physically removed or tampered with, reducing the risk of SIM cloning or unauthorized SIM swapping.
Because they are a more recent technology, eSIMs also have additional security features like remote provisioning and encrypted communications, which make them safer to use.
All that said, eSIMs are not infallible. Just like physical SIM cards, they can be hacked into by an attacker with enough skills and determination.
As an eSIM user, you can protect yourself by using strong, unique passwords, keeping your eSIM software updated, and only downloading profiles from trusted sources.
