Travelling unprepared can quickly strain your mobile connectivity. Roaming charges can cost a small fortune, and without connectivity, you could quickly lose key features in banking apps, travel companions, and more.
That’s why it’s crucial to equip yourself with an eSIM before you travel. An eSIM ensures you can stay connected to friends and family in other countries and continue using apps needing verification as usual, all without overspending in the process.
But, no eSIM does this quite as well as Saily, the eSIM from the team behind NordVPN. Saily gives you access to not only your data while abroad, but also calls and texts through an optional US phone number, plus built-in tools like an ad blocker, virtual location, and malicious link blocking.
- Saily lets you add a dedicated (+1) US phone number from $1.99/month, allowing you to receive banking authentication codes over SMS and make calls
- Saily uses one single, reusable eSIM profile across 200+ destinations without reinstalling profiles or scanning new QR codes
- Saily’s Ad Blocker cuts mobile data consumption by up to 28.6%
- Saily includes web protection to block phishing links and 115+ virtual locations
How does Saily phone number work abroad?
Saily’s phone number provides travelers with a real, dedicated (+1) US phone number directly in the app alongside your data plan. This phone number helps you to receive SMS verification codes or access US banking apps that may require you to have a US phone number.
To use Saily to regain access to key services requiring two-factor authentication, all you need to do is:
- Download the Saily app
- Choose your Saily data plan
- Add the US phone number add-on
- Download your eSIM to your device
- Set up two-factor authentication on your apps to your new Saily phone number
- Travel anywhere, risk-free.
A phone number subscription starts from $1.99 per month; this is before adding the calls and texts you need for your specific region, though this can cost as little as $0.99 depending on how many you need. As with your data plan, you can add calls and texts by region as and how you require.
Most popular eSIM apps focus primarily on offering data, due to the huge popularity and use of social media. But many overlook that services requiring two-factor authentication may not offer options beyond traditional SMS.
In these cases, if you don’t have free access to texts through your normal provider, you could end up paying hugely inflated fees to access services like banking, taxi booking, and more. If you’re enjoying your holiday or working abroad, this could quickly leave you stuck without the tools you need to travel or access key documents and itineraries for your travels.
One eSIM plan from Saily can include minutes and texts alongside your data allowance when you add the US phone number add-on, meaning you can use your eSIM to verify every account you might need while travelling.
Key benefits of Saily’s dedicated US phone line:
- Receive unlimited free texts over SMS without an active calling plan
- Outgoing calls connect to local numbers within your active plan's coverage area, while incoming calls can be received from anywhere in the world
- Your Saily number is persistent and remains constant across every trip, keeping travel-related communications separate from your personal number
- Because the number is persistent, it stays the same even when you switch data plans or cross into new geographic regions
Can one Saily eSIM work in multiple countries?
Yes, a single Saily eSIM profile works across 200+ countries and regions. Unlike other providers that force you to download a new eSIM profile or scan a fresh QR code for every border crossed, Saily runs on a single, reusable profile. That means you can stay connected in any country from the moment you land, without needing to install an eSIM all over again.
You needn’t worry about your Saily phone number either. It works no matter which data pack you have linked to your Saily account, meaning you’re never without the connectivity you need to contact family and friends while on the go. What’s more, if you’re travelling on a cruise, dedicated Cruise plans use cellular-at-sea networks to access mobile data as usual while you’re on the go.
All these choices are available in the Saily app. This means you can adjust your plan as and when you need to without switching back and forth between the website and your phone. This also prevents you from needing to regularly add your payment details in multiple places, since the Saily app houses your account and every plan you need to stay connected while travelling.
Built-in digital security features in Saily
It’s not just about keeping everything you need in one app. Saily also ensures you only use what you need, and don’t encounter anything that could leave you at risk.
One way it does this is with its built-in ad blocker. Blocking ads can reduce your data usage by up to 28.6%, which could be all the difference between only paying for what you need and overspending on data you won’t need. This also helps protect you against unwanted tracking from the sites you use while away.
Saily also integrates malicious link blocking. This means that if you accidentally tap a fake link claiming your flight is delayed, or you make the mistake of scanning an unsafe QR code, Saily blocks the page before it loads and keeps your identity and bank details safe. What’s more, this is built from NordVPN’s next-gen antivirus capabilities, which TechRadar has seen to be among the best VPN antivirus tools available in 2026.
If you’d rather just use links you're familiar with, you can also use Saily’s virtual location function to access search services as though you were in your home country. Saily offers more than 115 virtual locations, meaning you should never be stuck without quick, safe access to the links you need, no matter the country that you are in.
Saily’s many features are all available to set up and use within its app. That means no confusion between website setups, no need to continuously login to access what you need, and, most importantly, quick access to the tools, and plans you need to ensure you can always call, text, and search as you would as if you’re at home.
