The best T-Mobile deals for May 2026: iPhone 17, Galaxy S26 Ultra, Google Pixel 10 Pro XL

Apple iPhone 17 series: up to $1,100 off with a trade-in and plan at T-Mobile
T-Mobile's headline deal on the iPhone 17 series is a trade-in rebate of up to $1,100 - an impressive sum that even get you a device included if you go for the standard model. Note, unlike some deals at the carrier, you do need to trade-in to be eligible here, and you also need a line on an Experience More plan to hit the maximum rebate. The cheaper plans still have discounts of up to $830 this week, however, so there are still great options there.

Apple iPhone 17: included with a switch at T-Mobile
T-Mobile's latest deal on the iPhone 17 offers a diverse range of discounts. Alongside the usual trade-in rebates, those who switch over from a rival carrier this week can get a device included on either an Experience Beyond or Better Value plan. That's a deal that doesn't even require the usual trade-in criteria, so it's a strong option if you don't have a device ready to trade in.

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.

Samsung Galaxy S26 Ultra: up to $900 off with a new line (no trade-in) at T-Mobile
My favorite T-Mobile Android deal this week is definitely the carrier's current promotion on the excellent Galaxy S26 Ultra. Right now, you don't have to trade in to get a massive discount of up to $900 on this device if you sign up for a new line. While that's not enough to cover the entire cost of the device, it's a great discount on a phone that usually comes with a hefty asking price.

Google Pixel 10 Pro XL: included with a new unlimited line at T-Mobile
T-Mobile's deal on the Pixel 10 Pro XL has to be one of the strongest on the entire carrier site right now. As with the promotion on the S26 Ultra above, you don't need to trade-in to get a massive discount on this premium device this week. You can, in fact, get it included with a new line on the higher-end Experience Beyond plan right now.

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: $200 back after 14 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 10 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's prepaid gift card will also throw in that $300 prepaid card. While pricey, this particular plan includes a handy range extender and subscriptions to Hulu and Paramount+ Essential bundled in.

Samsung Galaxy Tab S10 FE: $275 off with new tablet line
One of the best tablet deals you'll find at T-Mobile this week is on the Samsung Galaxy Tab S10 FE. This mid-range slate packs in a decent chipset and display, so it's an easy recommendation with its massive $275 discount at the carrier this week. A new line is required, however, as with the other tablet deals on our list.

Apple Watch Series 11: buy one get $300 off second at T-Mobile
Got your eye on the new Apple Watch 11? T-Mobile's current promotion offers a massive $300 discount when you buy two devices together, which could be a great option for multi-line users looking to pick up some accessories on the cheap.

Apple Watch SE 3: $200 off with new line, or buy one get $300 off second at T-Mobile
It's not just the Apple Watch 11 that's available with a superb discount at T-Mobile this week. You can also get the Apple Watch SE 3, which is the latest budget-oriented smartwatch from the brand. With today's discount, you can add this device to a cellular plan and pay just $99 in full, thanks to a massive $200 discount.

Samsung Galaxy Watch 8: free with a new watch line
Got an Android phone? Right now, you can get a brand-new Galaxy Watch 8 to go alongside your new phone when you pick it up alongside a new watch cellular plan. Considering this device is currently valued at $399, this is easily one of the best accessory 'freebies' available at T-Mobile.
