Some T-Mobile customers who've held onto old phone plans are being notified that their accounts will soon be automatically upgraded to the company's current lineup of plans, which in some cases will mean an increase in their mobile phone bills.
A representative of T-Mobile chose to not share which plans are being retired, but said some of them stretch back 10 to 15 years. That could include Simple Choice, T-Mobile One, One Plus and Magenta family of plans, as well as grandfathered Sprint plans that carried over when T-Mobile and Sprint merged in 2020.
The change affects thousands of customers and will apply within the next few weeks, to be reflected on the next billing cycles. Affected subscribers, which also includes some small businesses, should expect to get the news via text or through the T-Life app starting today.
It's not unusual for companies to take action to shake people off older plans. AT&T added a fee to some of its legacy plans in May, and T-Mobile added price hikes in March 2025. What's different here is that T-Mobile is taking action directly and automatically, versus encouraging its customers to upgrade.
Allan Samson, chief marketing officer at T-Mobile, explained during a briefing late last week that "absolutely nothing is required of the customer, and it just is going to happen."
He said the legacy plans will be moved to comparable modern plans in the current lineup, which includes Essentials, Essentials Saver, Experience More, Experience Beyond and Better Value. That will bring more features such as expanded international roaming, premium 5G speeds and greater hotspot data than what are available on their older plan.
For customers who do see a price increase, "the price they're going to be paying in a huge majority of cases is still going to be below what that exact plan sells for today," said Samson. "We're not moving you all the way up to the rack rate" that a new customer would pay.
If you've been moved to a new plan and aren't happy with the one that's been chosen for you, your only options will be to shop for a new T-Mobile plan or look for a new provider.
Modernizing internal systems
At the heart of the move is a need to reduce complexity in the company's internal systems.
