T-Mobile Customer Data Breach Litigation
Case Overview
In August 2021, T-Mobile USA disclosed one of the largest telecommunications data breaches in U.S. history, in which a hacker exploited vulnerabilities in the company's network to steal sensitive personal information belonging to approximately 76.6 million individuals. The stolen data included full names, Social Security numbers, dates of birth, driver's license information, IMEI device numbers, and account PINs. Plaintiffs alleged that T-Mobile had failed to implement reasonable and industry-standard cybersecurity safeguards despite being aware of prior security incidents and known vulnerabilities, making the breach not merely an act of sophisticated hacking but a foreseeable consequence of the company's systemic negligence.
T-Mobile agreed to a $350 million class action settlement in 2022 — one of the largest data breach settlements in U.S. history — to resolve claims brought by affected customers. Class members were eligible to receive cash payments for out-of-pocket losses and up to 25 months of free identity protection services. In addition to the monetary fund, T-Mobile committed to spending $150 million on data security improvements through 2023, representing a rare structural-remedy component in consumer data breach litigation. The case set an important precedent for corporate accountability in cybersecurity negligence and spurred broader regulatory scrutiny of data handling practices across the telecom sector.
Who May Qualify
Current, former, or prospective T-Mobile customers whose personal information was compromised in the August 2021 data breach, including those whose Social Security numbers, driver's license data, or account information was exposed.
