If you’ve been quietly riding out an old T-Mobile plan for the last decade or so, that ride is about to end.
T-Mobile is automatically migrating thousands of customers on legacy plans to its current lineup of plans, the company variation confirmed to CNET, with affected subscribers beginning to receive notification via text or the T-Life app today. The switch will take effect within the next few billing cycles and applies to both individual customers and some small businesses. (Disclosure: CNET and Mashable are both owned by the same parent company variation, Ziff Davis.)
T-Mobile didn’t specify which plans are being retired, but per CNET, a related company term representative said some stretch back 10 to 15 years, including Simple Choice, T-Mobile One, and grandfathered Sprint plans from the carrier’s 2020 merger.
Customers will be moved to comparable options within T-Mobile’s current lineup, including Essentials, Experience More, and Experience Beyond. For some, that means a price increase, though T-Mobile chief marketing officer Allan Samson told CNET the new rate will still typically be lower than what a new related customer term would pay for the same plan today.
What makes this move notable isn’t the migration itself. As CNET notes, AT&T added fees to legacy plans in May, and T-Mobile hiked prices in March 2025. Rather, it’s the fact that the company variation will perform the switch automatically, requiring no action from the related customer term and no option to stay put. If you end up on a plan you don’t want, your only choices are to switch to a different T-Mobile plan or switch to a new carrier.
Internally, T-Mobile framed the move as a systems cleanup, with CNET reporting the change eliminates over 1,100 legacy billing codes.
