It’s worth noting that carriers constantly update their deals. The best offers usually happen around new phone launches — typically February or March for Samsung Galaxy S phones, September for Apple iPhones and fall for Google Pixel phones — and around holiday shopping events, like Black Friday. We’ll continue to update this page as offers come and go and new phones hit shelves, so be sure to check back again to find the latest deals at any given time.
Best T-Mobile phone deals
Many of T-Mobile’s phone deals are available to new and existing customers, although trade-ins are often required to get the advertised prices. Keep in mind the deals are split across 24 months of bill credits, meaning you’ll need to remain a T-Mobile customer for at least two years for the phone to get paid off as the terms state. If you cancel before that period is over, you’ll be responsible for any remaining charges.
Apple iPhone 16 series
T-Mobile is offering a few different trade-in discounts depending on which service plan you have. People on a Go5G Next plan can save up to $1,000 with an eligible trade-in, which scores you the basic iPhone 16, 16 Plus or 16 Pro for free. Those on a Go5G Plus plan will still get up to $830 off with an eligible trade-in, which scores you the basic model for free. If you’re on a basic plan, the most you’ll save via trade-in is $300. T-Mobile is also offering up to $830 off when both trading in an old device and activating a new line of service.
T-Mobile also has some exclusive offers available to military members, first responders and those over 55. If you qualify for these special discounts, you can save up to $630 with a trade-in on a Go5G Plus or Next plan, or with both a trade-in and the addition of a new line on other qualifying plans.

Best T-Mobile plan deals
If you’re looking to make the switch to T-Mobile, there are a few deals on various plans that might make you lean toward one or the other. Promotions on plans are less common these days, although oftentimes you can get some free extras, like streaming service subscriptions, music subscriptions and extra travel data, with enrollment in some of the higher-end 5G plans from each carrier, including T-Mobile.
3rd-line discounts
Customers who are looking to move to T-Mobile and sign up for three lines of service will be happy to hear that the carrier is offering a buy two, get one free promotion, meaning your third line won’t cost you anything. This offer is available to those on its Essentials, Go5G or Go5G Plus plans. For those on a Go5G Next plan, the third line is discounted to just $10 per month.
Military and first responders
T-Mobile offers active-duty military, veterans and first responders $5 off the cost of monthly service, which brings the base price of the plans down a little per line with autopay enabled.
Discounts for folks 55 or older

The Plus and Next plans also come with free bonuses like a one-year AAA membership, a free Netflix subscription and more.
FAQ
Are T-Mobile deals available to existing customers? Or only new ones?
Up until recently, T-Mobile heavily favored new customers with its best deals, leaving behind folks who were loyal to the carrier. That’s since changed, and now most of the offers are available for both new and existing customers under the same terms.
How do T-Mobile’s discounts work?
It’s easy to see up to $1,000 off the price of something and get excited, but you’ll want to make sure you know what you’re signing up for. T-Mobile applies these discounts as bill credits that are usually spread out across 24 months. Sometimes, part of the discount amount is given in the form of a prepaid gift card (for a trade-in) and the rest is done as bill credits, but that’s specified when it’s happening.
What happens if you leave T-Mobile before the 24 months are up?
If you don’t stick with T-Mobile through the full 24 months of bill credits, you’ll be responsible for all the remaining charges. Before canceling or transferring your service to another carrier, be sure to reach out to T-Mobile to understand what you’ll actually owe, to ensure you can cover that before making the move.
