Galaxy S25 users on T-Mobile should be receiving a fresh update now, along with their first taste of seamless updates in One UI.

Later in November, the site Smartprix pointed to a June release thanks to the addition of a phone with the model number SM-S937U being added to the GSMA IMEI database. In general, once Samsung adds a device to that database you can to see it released in six to seven months, suggesting a June release date.

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).
