T-Mobile has suffered more confirmed data breaches than any other major U.S. wireless carrier. Between 2021 and 2023, a series of incidents exposed the personal data of tens of millions of customers — Social Security numbers, driver's licenses, addresses, and financial information. Multiple class action settlements resulting from these breaches are active or pending in 2026.
T-Mobile Breach Timeline
- August 2021: 76.6 million U.S. residents exposed — names, SSNs, driver's license numbers, dates of birth, phone numbers. One of the largest telecom breaches in U.S. history.
- January 2023: 37 million accounts accessed via a misconfigured API — names, billing addresses, email, phone numbers, account numbers.
- April 2023: 836 customers had accounts accessed through a coordinated attack.
The 2021 breach generated the primary class action settlement ($350 million fund). The 2023 breaches are in active litigation and may produce additional settlement opportunities.
Who Qualifies for T-Mobile Settlement Claims?
You likely qualify if you were a T-Mobile, Sprint, or Metro by T-Mobile customer at any point between 2019 and 2023. Former Sprint customers are included — T-Mobile acquired Sprint in 2020 and breached data included legacy Sprint records. You do not need to have experienced identity theft. Being a customer whose data was in the breached database is sufficient for base compensation claims.

How Much Can I Get?
The 2021 settlement's $350 million fund distributed among eligible claimants. Average payouts run $25–$100 per claimant for base claims depending on total claim participation. Customers with documented identity theft from the breach were eligible for higher compensation (up to several thousand dollars) through a separate enhanced claims track. T-Mobile also provided two years of free identity protection services through McAfee as part of the settlement.

I cancelled my T-Mobile service years ago. Can I still file?
Yes. Class membership is based on when your account was active, not your current status. If your account was active during a breach class period, you are a class member regardless of whether you are still a subscriber.
I never got a breach notification from T-Mobile. Does that disqualify me?
No. T-Mobile failed to notify many affected customers. Non-notification does not disqualify you from settlement participation.
Can I file claims for the 2021 AND 2023 breaches?
If separate settlements exist for each breach and you were a customer during both class periods, yes — you can file separate claims for each covered incident.
