Common questions

How much does the T-Mobile 2021 Data Breach Settlement pay?
The total settlement fund is $350M. Actual amounts depend on how many valid claims are filed — most settlements divide a fixed fund pro rata, so a higher claim rate means a smaller individual check. An "up to" figure is a cap, not a guarantee.
What is the claim deadline for the T-Mobile 2021 Data Breach Settlement?
This settlement is closed to new claims — the deadline was January 23, 2023. Once a claim deadline passes you generally forfeit your share, even if you qualified.
Is the T-Mobile 2021 Data Breach Settlement notice real, or a scam?
Kroll Settlement Administration is the settlement administrator for this case. Claims are filed at kellerrohrback.com. Filing a class action claim is always free — no legitimate settlement charges you to claim, and no administrator will ask for payment, a gift card, or your full Social Security number by email or text. If a notice asks for any of those, it is not from the administrator. When in doubt, ignore the link you were sent and go to the official settlement website directly.
When will payments from the T-Mobile 2021 Data Breach Settlement be sent?
Class action payouts typically take 12 to 24 months after the claim deadline, and longer if the settlement is appealed. The final approval hearing for this case is set for June 29, 2023; no payments can be issued before a settlement receives final approval.
