T-Mobile automatically moves legacy plans, $4 price rise

T-Mobile is automatically migrating thousands of customers from legacy wireless plans to its current lineup, a move that will result in price increases for some subscribers. The company confirmed the plan retirement and automatic transition on Monday, June 29, 2026, with notifications beginning to reach affected customers via text message and the T-Life app.

The carrier is retiring plans that date back 10 to 15 years to the 3G and 4G eras. While T-Mobile did not officially publish a full list, the plans in question are widely reported to include Simple Choice, T-Mobile ONE, ONE Plus, the Magenta family of plans, and grandfathered Sprint plans carried over from the 2020 merger. Customers will be moved to comparable modern plans such as Essentials, Experience More, and Experience Beyond.

Company executives framed the change as a necessary systems cleanup. In an internal email, Chief Operating Officer Jon Freier stated the retirement clears out over 1,100 legacy billing codes, simplifying a complex infrastructure that had grown from maintaining both T-Mobile's and the acquired Sprint's systems. He said the simplification would allow the company to focus resources on customer experience.
