T-Mobile retires legacy plans, moving customers to newer rate plans
T-Mobile is moving legacy customers off 3G- and 4G-era plans, with some bills rising about $4 a line. The switch starts on mid-July bill cycles.
T-Mobile began notifying customers today that it is retiring many of its oldest rate plans and moving them onto current options, with notices arriving by text message or through the T-Life app. The change is set to hit customers on their next billing cycle, starting in mid-July, and the average adjustment is about $4 per line, though some subscribers will see no change while others will pay more depending on the plan and line type.
The migration reaches back to plans built nearly 15 years ago, from the 3G and 4G eras before T-Mobile’s 5G network was fully deployed. More than 1,100 legacy plan codes are being closed, and the affected base includes Simple Choice, ONE and ONE Plus, Magenta, grandfathered Sprint plans and some small-business accounts. The move is mandatory, with no action required from customers and no option to stay on the old plans.
Customers moved to the newer plans will keep their current benefits and gain access to newer features, along with a 5-year price guarantee on talk, text and 5G data, excluding taxes and fees. T-Mobile introduced Experience More and Experience Beyond on April 22, 2025. Those plans were designed around that 5-year guarantee. T-Mobile completed its Sprint merger on April 1, 2020, making the Sprint-branded legacy accounts part of the same customer base now being folded into the newer lineup.
