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).

Save up to $1,000 on a new phone at T-Mobile with a new line and/or trade-in. The best part? You might just get a free phone out of these deals.

Looking to get your hands on the top Galaxy S25 Ultra variant for your money? Unfortunately, your options are very limited in the US.
