If you’re after a new iPhone without breaking the bank, T-Mobile’s current deals offer some of the best value around—especially if you’re switching carriers or adding lines. The savings can be huge, and the phones? Brand new.
T-Mobile is handing out free iPhone 17s when you switch to their network and add a line. This isn’t one of those gimmicks where you pay now and maybe save later. Instead, T-Mobile applies monthly bill credits for 24 months that cover the full price of the phone. You’ll need to sign up for a qualifying plan, but if you’re already thinking of switching, it’s an easy win. No trade-in is required for this offer, which makes it perfect if you’re holding onto an older phone.
You can also qualify for this deal with just a single line. Whether you’re a solo user or grabbing a new phone for someone else, this offer is simple and surprisingly generous. Just keep the service active, and the credits keep coming.
Family Deal: 4 iPhones for $100
One of the most talked-about offers this season is the T-Mobile family bundle: four iPhone 17s and four unlimited lines for just $100 per month total. That’s right—four phones, four lines, and no trade-in needed. It’s especially great for families upgrading from older devices or switching from another carrier. The math breaks down to $25 per line, and with the iPhone 17’s retail price starting at around $800, the savings here are enormous.
This deal does require four new lines to qualify, so it’s best suited for families or friend groups looking to bundle. Once set up, you’ll receive monthly bill credits covering the phones, and your total service cost stays locked at a very budget-friendly rate.
Up to $1,100 Off with Trade-In
Have an old iPhone or other qualifying smartphone lying around? T-Mobile’s trade-in program could get you up to $1,100 off a new iPhone 17 Pro or Pro Max. This deal works by applying your trade-in value as a down payment, followed by 24 months of bill credits to cover the rest. It’s ideal if you want a higher-end model like the iPhone 17 Pro Max without paying the full price upfront.
To get the biggest discount, your trade-in device needs to be in good condition and relatively recent. But even older phones can earn decent value toward the latest models, making this a smart option for anyone upgrading.
No Trade-In? No Problem
Not ready to give up your current phone? You can still score major discounts on new iPhones by simply adding a new line. This is a standout feature of T-Mobile’s offers—many don’t require you to hand over a device. Instead, they focus on growing their user base, so if you’re bringing in a new number or setting up a fresh line, you’re likely eligible for serious savings.
This setup works especially well for people who want to keep a backup phone or pass their current device to a family member. It’s a flexible option that still gives you access to a new iPhone without giving anything up.
What to Know About Bill Credits
T-Mobile’s deals aren’t instant discounts. Instead, they use a bill credit system that spreads the savings across 24 months. You’ll get the phone upfront or finance it through T-Mobile, and each month they’ll apply a credit to your bill to reduce the cost. If you keep your line active for two years, the total credit will match the phone’s value.
Cancel early, and the bill credits stop—leaving you responsible for the remaining balance. That’s why this deal is perfect for people planning to stay put and enjoy consistent savings over time.
These iPhone Deals Won’t Last
These promotions are tied to the holiday season, and like most good things, they’re not going to last forever. T-Mobile has rolled out aggressive offers to close out the year, especially around new customer sign-ups and family bundles.
If you’re thinking of making a move, now’s the time. Inventory may change and certain models could sell out. And once the new year hits, prices and offers will likely reset. Getting in now ensures you’ll lock in the best value for 2025.
Don’t Miss Out on a Great Upgrade
Whether you’re upgrading your own device, outfitting the whole family, or simply ready to stop overpaying with your current provider, T-Mobile’s iPhone deals offer outstanding value without the headache. With flexible options for both trade-in and non-trade-in customers, these deals are generous and easy to take advantage of. If the new iPhone 17 is on your wishlist, T-Mobile has made getting one more achievable than ever.
