T-Mobile customers can get a new Galaxy S25 series phone for free. How to qualify

Samsung unveiled its newest lineup of Galaxy S25 smartphones last week at its Unpacked event in San Jose, California. This includes three new phone models — the Galaxy S25, Galaxy S25+, and Galaxy S25 Ultra, all of which are available for preorder now.

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 — including T-Mobile. At the time of writing, we’re seeing several offers on all three of the new Galaxy S25 smartphones.

So what are the best T-Mobile offers on the new Samsung Galaxy S25 lineup? Our pick is snagging the Galaxy 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. 

Plus, new and existing customers can also take advantage of similar offers for a limited time, including getting the Galaxy S25+ for free (or up to $1,000 off on any phone in the series) when trading in any eligible device in working condition on T-Mobile’s Go5G Plus plan. 

If you’re eyeing the base model Galaxy S25 — don’t fret. You can also get one for free (or up to $800 off any phone in the series) if you add a line on a Go5G Plus/Next plan or if you trade in an eligible device in working condition and add a line on a Go5G plan (or most other plans).

The majority of customers can score up to $500 off any phone in the Galaxy S25 series when trading in an eligible device in working condition on Go5G or most plans, too. Keep in mind that all of these offers are available via 24 monthly bill credits (plus tax), and if you order in the T Life app or via t-mobile.com, you’ll be eligible for free next-day shipping and free activation for a limited time. 

Business customers can also swipe up new Galaxy S25 offers, like grabbing the Samsung Galaxy S25+ for free (or $1,000 off any phone in the series) when adding a line on Business Unlimited Ultimate or Business Unlimited Edge with no trade-in required. And if you’re a new customer switching to T-Mobile, you’ll get an extra $200 off.
