| 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 | Pending, not accepting claims yet |
| Claim deadline | None announced |
| Estimated payout | No settlement yet. The price lock case seeks refunds of rate increases on legacy plans. The 2021 data breach settlement ($25, or $100 in California, up to $25,000 in losses) closed to claims in January 2023 and has paid out |
| Proof required | Not stated |
| How to file | No claim form available |
There is no open class action lawsuit T-Mobile customers can file a claim in right now. The $350 million data breach settlement stopped taking claims on January 23, 2023, and its payments went out by May 30, 2025. The case people are watching, over rate hikes on “price lock” plans, is still before a federal judge in Seattle, and the carrier wants it moved to individual arbitration.
The $350 Million T-Mobile Data Breach Settlement Is Paid and Closed
The company agreed to settle with no admission of wrongdoing, and the deal is finished. It covered the August 2021 cyberattack, which exposed 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, with final approval on 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 |
Money went out by PayPal, Venmo, Zelle, direct deposit, or check, whichever each person chose. Class members who never filed a T-Mobile settlement claim have nothing left to collect. Reports said leftover funds could be split among claimants later; only the official settlement site would announce that.
The 2023 Breach Has No Payout Yet
Nobody hit by the 2023 incident has been offered money. On January 5, 2023, the company found a bad actor pulling names, addresses, emails, phone numbers, and birth dates through one API for about 37 million accounts. Class actions followed, and the carrier’s June 2026 quarterly SEC report still lists them as unresolved.
Some sites describe a “$150 million” second settlement. We couldn’t find one. That figure is what the 2021 deal required the company to spend on security in 2022 and 2023. The $31.5 million FCC agreement from September 2024 was a fine plus security upgrades, so it paid no customers. Our data breach settlement list tracks cases that are paying.
The Price Lock Lawsuit and the Arbitration Fight
This is the live case. 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 ties that promise to a 2020 pledge not to raise rates for three years after the Sprint merger.
What most coverage skips: the named plaintiffs say they used the opt-out in the arbitration clause. Most customers never did, which is why the company has asked the judge to compel arbitration and pause the case. The suit moved from New Jersey to the Western District of Washington in August 2025, and that motion was still being briefed in April 2026. Separately, lawyers are signing people up for mass arbitration.
Two Newer Suits in Early Stages
- 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.
If you’re on a legacy price lock plan, save your plan confirmations and rate increase notices now, since any future payout would likely ask for them. Before trusting anyone who says a class action lawsuit T-Mobile customers can join is open, check the case docket or an official administrator site. Our guide on how to join a class action explains what happens once one is.
FAQ
How do I join the T-Mobile lawsuit?
You can’t file in any case right now. The 2021 claims closed in January 2023, and the price lock case has no deal. If one is reached, notices and an official claim site will follow.
How much will I get from the T-Mobile settlement?
Those who filed in the 2021 case got $25, or $100 in California, plus up to $25,000 for documented losses. Those went out by May 30, 2025. No other case has a payout amount yet.
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. The 2023 incident hit about 37 million accounts. Missing that notice costs you nothing yet, since there’s no deal to claim from.
