In 2021, the cellular wireless network company T-Mobile experienced a major “data breach” that caused the personal information of millions of their customers to be exposed to potential hackers. A class action lawsuit was filed against T-Mobile on behalf of all wireless customers who had their information exposed. That lawsuit eventually resulted in a $350 million settlement available to all impacted customers. On this page, we will explain the story behind the T-Mobile customer data breach lawsuit and outline the details of the settlement.
Following a cyberattack in 2021 that exposed the personal information of millions of customers, T-Mobile reached a settlement of $350 million to address allegations of negligence leading to the breach. This settlement marked the second-largest in U.S. history for a data breach, with Equifax’s $700 million settlement in 2019 being the largest.
The deadline for submitting claims to be part of the substantial payout was Monday, January 23, 2023. However, shortly before this deadline, on January 19, 2023, T-Mobile disclosed another cyberattack that affected a minimum of 37 million current customers.
