When you trade in your old phone with T-Mobile, you'll get it for free. New and existing customers can swap an old device in any condition for a new Galaxy S25+ for free, or use the credit for up to $1,000 off other models like the top-of-the-line Samsung Galaxy S25 Ultra (delivered as 24 monthly credits on your bill).

The Galaxy S25 Plus is a tougher sell given how it shares the same set of Galaxy AI features and cameras found on the cheaper S25 model. It's a powerful, big-screen phone, but it's hampered by a dimmer display and modest battery life improvements over its predecessor.

We’re now keeping our phones longer between upgrades, which is why the guaranteed minimum support periods are extending across the board. It is clear that this update decision from Samsung will affect millions of users, and while three-monthly updates is better than no updates, it doesn’t help when there’s an urgent fix mid-cycle.
