The 2021 Breach and the $350 Million Settlement
T-Mobile disclosed in August 2021 that a criminal cyberattack had compromised personal information belonging to approximately 76 million current, former, and prospective customers, in a breach that began around August 3, 2021. The resulting lawsuits were consolidated into a multidistrict litigation in federal court in Missouri, and T-Mobile agreed to a 350 million dollar settlement without admitting wrongdoing, which received final court approval in June 2023 after resolving related appeals.
Under the settlement, class members who filed a timely claim could receive a flat payment, generally in the range of 25 to 100 dollars depending on state of residency, or up to 25,000 dollars for documented extraordinary losses tied to the breach, along with two years of credit monitoring and identity theft protection services. T-Mobile also committed to spending an additional 150 million dollars on data security improvements as part of the settlement.
Payments Are Now Complete
The claim deadline for this settlement was January 23, 2023, and that window closed long ago, meaning no new claims can be submitted for the 2021 breach settlement today. After a fee-related appeal delayed the process, distribution of payments finally began in 2025, and according to the official settlement website, all settlement payments had been issued as of May 30, 2025.
Anyone who submitted a valid claim before the deadline should have already received payment. If you believe you filed a valid claim but never received payment, contacting the settlement administrator directly is the appropriate step, rather than assuming a new claims process exists.
A Separate, More Recent FCC Settlement
This should not be confused with a separate matter: in 2025, T-Mobile agreed to pay 31.5 million dollars to resolve multiple Federal Communications Commission investigations covering a pattern of data breach incidents from 2021, 2022, and 2023 that combined affected millions of consumers. This is a regulatory settlement between T-Mobile and the FCC, distinct from the consumer class action described above, and does not provide direct payments to individual consumers in the way the class settlement did.
Because T-Mobile has experienced more than one breach-related legal matter in recent years, anyone researching this topic should confirm which specific incident and settlement, the 2021 consumer class action or the more recent FCC regulatory action, applies to their situation.
How to Get Legal Help
The claim deadline for the main $350 million settlement passed in January 2023 and all payments have been issued, so there is no new action to take for that specific settlement. If you receive a notice about a newer T-Mobile breach, verify it through official T-Mobile communications or the FCC before responding, since breach notifications are also commonly imitated in phishing scams.

T-Mobile Data Breach Class Action: The $350M Settlement Is Paid Out: Frequently Asked Questions
Answers to the most common questions about this case and your legal options.
What was the T-Mobile data breach lawsuit about?
A 2021 cyberattack compromised personal information for approximately 76 million people, leading to a consolidated federal lawsuit that T-Mobile settled for 350 million dollars without admitting wrongdoing.
Can I still file a claim?
No. The claim deadline was January 23, 2023, and all settlement payments were issued as of May 30, 2025. That claims process is closed.
How much did people receive?
Flat payments generally in the range of 25 to 100 dollars depending on state of residency, or up to 25,000 dollars for documented extraordinary losses connected to the breach, plus two years of credit monitoring.
Is the $31.5 million FCC settlement the same thing?
No. That is a separate, later regulatory settlement between T-Mobile and the FCC resolving investigations into a pattern of data breaches from 2021, 2022, and 2023, distinct from the 2021 consumer class action settlement.
What should I do if I get a new T-Mobile breach notice?
Verify it through official T-Mobile communications or FCC sources before responding, since breach notifications are frequently imitated in phishing scams, and confirm which specific incident it relates to.
