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 to File a T-Mobile Settlement Claim

  1. Search T-Mobile settlements on SettlementRadar
  2. Confirm your account was active during the relevant class period
  3. Navigate to the official settlement administrator's claim portal
  4. Enter the phone number or email associated with your T-Mobile account
  5. Submit and save your claim confirmation number

Most T-Mobile breach claims take under 5 minutes. No documentation required — your account history verifies eligibility.

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.

Frequently Asked Questions

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.
