| Case | Oddo et al. v. T-Mobile USA, Inc., No. 2:25-cv-01651 (transferred from D.N.J. No. 2:24-cv-07719) |
| Court | U.S. District Court for the Western District of Washington |
| Status | Sent to arbitration and stayed; reconsideration motion pending |
| Claim deadline | None. No class claim form exists |
| Estimated payout | None. The 2021 data breach settlement closed to claims in January 2023 and has paid out |
| Proof required | Not applicable |
| How to file | No claim form available |
No class action lawsuit T-Mobile customers can file a claim in is open as of October 31, 2026. In late September, the federal judge in Seattle handling the price lock case sent those claims to individual arbitration and paused the suit. The $350 million data breach settlement stopped taking claims on January 23, 2023, and paid out by May 30, 2025. The one new remedy is limited to New York.

The Price Lock Lawsuit Was Sent to Arbitration
Oddo v. T-Mobile, filed July 12, 2024, says rates rose $5 per line in May 2024 on plans sold with a lifetime price guarantee: ONE, Simple-Choice, Magenta, Magenta Max, Magenta 55+, Magenta Amplified, and Magenta Military. It moved from New Jersey to the Western District of Washington in August 2025.
Judge Richard A. Jones then granted T-Mobile’s motion to compel arbitration and stayed the case, a ruling Law360 reported on September 30, 2026. The named plaintiffs had argued they used the opt-out in the arbitration clause. They have asked the judge to reconsider, and the court docket sets the carrier’s response for November 5, 2026.
Where the Price Lock Case Goes Next
If reconsideration fails, there is no class to join, and each customer would have to pursue a refund alone in arbitration. A $5 increase is $60 a year per line, small next to the effort that takes, which is why law firms bundle such claims into mass arbitrations. The trade-offs of a class action versus going it alone apply here.
New York Accounts Get a Separate Price Guarantee Deal
On October 20, 2026, New York Attorney General Letitia James announced an agreement with the carrier over the same 2024 increases, valued at up to more than $38 million. It is a state enforcement agreement, not a class settlement, so there is nothing to file.
Under the agreement, eligible accounts are New York-billed ONE accounts opened between January 1, 2017 and April 30, 2019 still on that plan when prices rose. Notice must go out by email by March 19, 2027, and account holders then have 45 days to choose:
- Cancel. The company pays your last monthly recurring charge, plus a $25 cash card if a line runs on less than 5G service.
- Stay with a sub-5G line. A free 5G phone (up to $250) or a $150 credit, plus no rate increase before May 30, 2029.
- Stay with all-5G lines. The same rate freeze through May 30, 2029.
No option refunds the $5 increases already paid.
The $350 Million Data Breach Settlement Is Paid
The 2021 deal is finished. It covered the August 2021 cyberattack, in which hackers stole personal data, including Social Security numbers, of current, former, and prospective customers. The suits were combined as In re: T-Mobile Customer Data Security Breach Litigation, No. 21-md-3019, in the Western District of Missouri. T-Mobile agreed to pay $350 million to settle on July 22, 2022, and final approval came June 29, 2023.
| Benefit | Amount |
|---|---|
| Flat cash | $25, or $100 for California residents |
| Documented losses | Up to $25,000 |
| Lost time | Up to 15 hours at $25 an hour |
| Credit monitoring | 2 years |
That money funded claims submitted by class members, the legal fees of plaintiffs’ counsel, and administration costs, and the settlement contains no admission of liability or wrongdoing by any defendant. In exchange, class members who did not opt out released all claims over the attack. Those who never submitted a claim form have nothing left to collect. Reports mention a possible second payment from leftover funds; only the settlement administrator’s official settlement site would announce one.
2023 Breach Suits Were Dismissed, and the $150 Million Mix-Up
On January 5, 2023, T-Mobile found a bad actor pulling names, billing addresses, emails, phone numbers, and birth dates through one API, compromising about 37 million accounts. Its September 2026 quarterly SEC report says the consumer class actions over that breach were dismissed without prejudice. No payout exists.
Some sites describe a “$150 million” second settlement. No such deal exists in the company’s SEC filings; that is what the 2021 settlement required it to spend on data security and related technology in 2022 and 2023. The $31.5 million FCC agreement from September 2024 was a fine plus security upgrades, so it paid no customers. See the AT&T and Verizon pages for the other carriers, or the data breach settlement list for cases that are paying.
Fee and Gift Card Suits
- Hidden fee. Beets, filed October 29, 2024, says the $3.49 per line “Regulatory Programs and Telco Recovery” charge is revenue dressed up as a government fee.
- Gift cards. Filed November 12, 2025 for Californians who added lines for a promised $200 gift card that never came.
Neither has a settlement or claim form.
What Legacy Plan Customers Should Do Now
Save your plan confirmations and rate increase notices; any arbitration claim would need them. New York ONE plan holders should watch their email through March 2027. Before trusting anyone who says a class action lawsuit T-Mobile customers can join is open, check the docket or an official administrator site, and read how to join a class action.
FAQ
How do I join the T-Mobile lawsuit?
You can’t right now. The 2021 breach claims closed in January 2023, and the price lock case was sent to arbitration in September 2026. New York ONE plan holders get email notice by March 19, 2027, with nothing to file.
How much will I get from the T-Mobile settlement?
Those who filed in the 2021 case received $25, or $100 in California, plus up to $25,000 for documented losses, paid by May 30, 2025. No other case has a class payout.
How do I know if I was part of the data breach?
The company says it notified affected people as state and federal rules require. Neither the 2021 nor the 2023 breach has an open claim, so a missed notice costs nothing now.
