Some New York T-Mobile customers who were promised a price that would never change are getting a choice. Under a settlement with the state attorney general, T-Mobile must email them by March 19, 2027. They then have 45 days to cancel or stay with a monthly price frozen until at least May 30, 2029.
What happened
From about January 2017 through April 2019, T-Mobile sold certain T-Mobile ONE plans with a promise to "never change the price you pay." The company made that promise in press releases and in a video interview with its then-CEO. In May and June 2024, T-Mobile raised prices on some New York customers, including these. The increase was about $5 per line, or an average of $12 per account.
Who is covered
The deal covers T-Mobile accounts billed in New York that signed up for a T-Mobile ONE plan between January 1, 2017 and April 30, 2019. The account must also have still been on that plan when prices rose in 2024. The attorney general counted about 252,957 Price Guarantee plans enrolled by New Yorkers. Accounts billed in other states are not covered.
Your choices
Each covered account picks one path within 45 days of getting notice.
- Cancel, and T-Mobile pays the last month's recurring charge.
- Stay, and T-Mobile cannot raise the monthly recurring charge on that plan until at least May 30, 2029.
- If T-Mobile knows a line gets less than 5G service, canceling brings a $25 cash card.
- Staying brings a 5G phone for each such line, free for certain devices valued up to $250, or a $150 credit toward others.
The attorney general's office says these benefits are worth up to more than $38 million.
What to do
There is no claim form, no court and no settlement fund. T-Mobile must email notice by March 19, 2027. Accounts with no working email get a letter by U.S. mail and five extra days to choose. T-Mobile must also put a reminder on the first bill after the notice goes out. Watch your email, including spam, and decide inside the window.
What is still open
This is a state enforcement deal called an Assurance of Discontinuance, effective October 20, 2026. T-Mobile neither admitted nor denied the findings. It also agreed to pay the state $98,834.75 and to clearly disclose the terms and time limits of future price guarantees.
A separate private lawsuit, Oddo v. T-Mobile USA, Inc., was sent to individual arbitration in September 2026. The plaintiffs asked the judge to reconsider. The state deal says it does not take away anyone's private legal rights.
The takeawayIf you are a New York customer on an old T-Mobile ONE plan, watch for the email and choose within 45 days: cancel, or lock in your price.
