T-Mobile Data Breach Class Action Lawsuit
A class action settlement has been proposed in a case against T-Mobile US, Inc. and T-Mobile USA, Inc. relating to a data breach that T-Mobile announced on August 16, 2021.
A Motion for Preliminary Approval and to Direct Notice of Proposed Settlement to the Class was filed on July 22, 2022. Preliminary Approval of the Proposed Settlement was granted on July 26, 2022. Class Members should begin receiving Notice of the Proposed Settlement in late October. Please check the settlement website for updates.
The Court appointed Norman E. Siegel of Stueve Siegel Hanson along with lawyers from Keller Rohrback L.L.P. and Hausfeld LLP to serve as Settlement Class Counsel. The firms have led the case on behalf of consumer plaintiffs since the beginning of the federal multidistrict litigation pending in the U.S. District Court for the Western District of Missouri before District Judge Brian C. Wimes.

Earlier in the week, reports surfaced that hacking groups stole the data of up to 100 million people from T-Mobile’s servers and were selling a portion of it on an underground “dark web” internet forum for 6 bitcoin, or approximately $280,000.
T-Mobile later confirmed that at least 54 million people had their information compromised, including 40 million former or prospective customers who were not current customers but had previously applied for credit with the carrier. More than 13 million victims are current “postpaid” customers—or T-Mobile customers who get billed at the end of each month. The victims had their full names, dates of birth, social security numbers, and driver’s license information stolen. 850,000 prepaid customers—who fund their accounts in advance—had their names, phone numbers, and PINs exposed. It is very possible that additional victims will be identified as T-Mobile’s investigation into the breach is ongoing.
Stueve Siegel Hanson partnered with co-counsel from Tousley Brain Stephens, MoginRubin, and Hausfeld to file the lawsuit against T-Mobile in the U.S. District Court for the Western District of Washington. Among other claims, the lawsuit asserts claims for negligence, unjust enrichment, and violations of the California Consumer Privacy Act and seeks damages and injunctive relief resulting from the breach.
