Thankfully, you won't have to spend a pretty penny to get your hands on the latest Galaxy S25 models, with promotional offers and prices  available from major mobile carriers -- includingT-Mobile . Plus, we're still seeing several offers on all three of the new Galaxy S25 smartphones, even a few weeks after their initial launch. 

So what are the best T-Mobile offers on the new Samsung Galaxy S25 lineup? Our pick is snagging theGalaxy S25+ for free (or receive up to$1,000 off any phone in the series) when trading in any eligible device in any condition on T-Mobile's Go5G Next plan. This limited-time offer means you'll get a new Galaxy phone no matter what condition your eligible device trade-in is in. As a person who never turns in their phone in "good" condition -- that's a good deal.
