The best T-Mobile deals for October 2026: iPhone 18 Pro, Google Pixel 11 series, Galaxy Z Fold 8, and more

iPhone 18 Pro series: up to $1,000 off with a new line, or with an eligible trade-in at T-Mobile
T-Mobile has pared back its deals slightly on the iPhone 18 series now the devices are no longer in the initial preorders phase. However, you can still get a very healthy discount of up to $1,000 off if you sign up for a new line on an Experience Beyond plan as a new customer. Alternatively, those who are looking to upgrade can trade in a device in any condition to get $1,000 off with a line on the Experience Beyond plan.

Apple iPhones: up to $830 off with a trade-in or new line T-Mobile
Not looking for a line on the highest-end plan? You can also get up to $830 off right now with a new line or trade-in on the mid-tier Experience More plan. This is available across most devices from what I can see, but I particularly think it's a compelling option on the standard iPhone 17. With this deal, you'll be paying just $100 over the duration of a 36-month plan, so it's quite a good option overall regardless of whether you're a new customer or an upgrader.

Apple iPhone 17e: get two devices included with a new line on the Essentials plan at T-Mobile
T-Mobile's latest deal on the fantastic new iPhone 17e lets you take home two devices when you switch over from a rival carrier. Even better still, no trade-ins are needed at all, and you only need a line on the entry-level Essentials plan to be eligible. That means a plan as cheap as $90/mo for two lines, thanks to the carrier's usual multi-line discounts.

Apple iPhone 15: four devices included on a $100/mo plan with a trade-in at T-Mobile
Looking for an affordable multi-line deal for your family? This promotion on the iPhone 15 at T-Mobile could be a good option. While the iPhone 15 is an older device now, you can get up to four devices included right now with a new unlimited plan. That includes the cheaper Essentials unlimited plan, which comes in at just $100/mo for four lines (or just $25/mo per line).

Samsung Galaxy S26 Plus: included with a new unlimited line (no trade-in) at T-Mobile
If you're more into your Android devices, consider T-Mobile's excellent promotion on the Galaxy S26. Right now, you can get this device included with a new line on an Experience More or Experience Beyond plan. As with the deal on the iPhone 17 above, no trade-ins are needed at all with this promotion, making it a very flexible option all around.

Samsung Galaxy S26 Ultra: up to $1,100 with a new unlimited line (no trade-in) at T-Mobile
Impressively, that same deal is also available on the Samsung Galaxy S26 Ultra this week at T-Mobile. While you can't quite score this hefty device on the house, you can still knock a decent $1,100 off this device's cost when you pair it up with a new unlimited line. Usually, you need to trade in an old device to get a discount like this, but right now, all that's needed is a new line on an eligible plan.

Google Pixel 11 series: get up to $1,000 off with a new line, or trade-in at T-Mobile
The brand new Pixel 11 series is officially available at T-Mobile, and the carrier has a really nice little deal that matches those you'll find on the latest iPhones. Essentially, to get the best possible discount ($1,000), you can either switch over to a new line on the Experience Beyond plan, or trade in a device to upgrade if you're already signed up.

Samsung Galaxy Z Flip 8 / Fold 8 / Fold 8 Ultra: up to $1,200 off with a trade-in and qualifying line
As you'd expect, T-Mobile has a range of enticing deals for the latest Galaxy Z Fold range. Usually, you'd be looking at paying serious cash for these high-end foldable devices, but T-Mobile is offering a choice between a massive trade-in rebate of up to $1,200 off, or a non-trade-in discount of up to $1,000 off. The non-trade-in deal here specifies that it's eligible 'with most plans', so this could low-key be the best bang for the buck options at the carrier currently.

Google Pixel 10a: included with a new line (no trade) at T-Mobile
If you're an Android user on a budget, check out this promotion on the Pixel 10a at T-Mobile this week. As with the other devices, this one is being included with a new unlimited data line. Unlike the higher-end phones, however, the plan eligiblity is a little looser here, meaning you don't need one of the higher-end plans to be eligible for a device.

T-Mobile Better Family plan: save up to $1,000 with three lines or more
T-Mobile was already a strong option for families, but the carrier has just unveiled a new promotion called the Better Family plan that's just notched things up further. This particular plan bundles in the carrier's highest level of streaming perks, unlimited mobile hotspot, and free phone upgrades every two years on a plan that starts at just $140/mo for three lines. It's not the cheapest plan available at the carrier, but you essentially get the super high-end perks for much cheaper here, making it a very strong option all around.

T-Mobile unlimited plans: get third line free
T-Mobile's excellent 'third line free' promotion has been a standout for a few years now, and I'm pleased to note that it's still available on all of the carriers' unlimited plans as an alternative to the Better Family plan above. Although single-line users won't find much joy here, families or those with multiple lines will be able to get their unlimited plans down to a minimum price of just $25/mo if they bundle four lines together on the Essentials plan.

Bring your own phone: get Essentials plan for $50/mo
A good option for single-line users, T-Mobile is currently offering a line on its entry-level Essentials unlimited plan for $50/mo when you switch over from another carrier. This equates to a $10/mo saving, so it's definitely worth considering, not least because the carrier will also gift you a virtual prepaid card of up to $800 in value to help pay off your phone at a rival network.

Military, first responder, and senior discounts: get Essentials plan for $50/mo
T-Mobile's unlimited postpaid plans are significantly cheaper if you're eligible for one of the carrier's discount criteria. Eligibility for a discount includes those over 55 years of age, first responders, or active serving military and veterans. You can't stack these discounts, but the savings roughly equate to $10 to $20 per month, depending on how many lines you have, so it's definitey worth applying for if you meet the criteria.

Amplified home internet: $100 back after 7 weeks
It's not just phone plans that are covered in this week's best T-Mobile deals, you can also find some good options if you're looking to switch up your home internet. Right now, for example, the carrier is offering a virtual prepaid Mastercard to home internet users after 7 weeks. Overall, a nice little discount for the first year of your contract.

All-in home internet: $200 prepaid card
And, if you want to upgrade to the high-end All-in home internet package, then T-Mobile will rebate you a full $200 after 7 weeks of service. While pricey, this particular plan includes a handy range extender and subscriptions to Hulu and Paramount+ Essential bundled in.
