The 2022 T-Mobile data breach affected 37 million T-Mobile customers, compromising at least your name, billing address, email, phone number, date of birth, T-Mobile account number and information such as the number of lines on the account and plan features. Further investigation may reveal that additional information was compromised. Data was accessed by a hacker in November 2022, and T-Mobile says it first detected the breach more than a month later. T-Mobile customers have suffered data hacks due to T-Mobile’s lax security eight times since 2018.


You may be affected if you are a current, former or prospective T-Mobile customer. Fill out the form to find out your rights. According to reports, the data was accessed on Nov. 25, 2022. As of Jan. 20, 2023, victims of the data breach have yet to be notified by the company directly if their information was breached. Of T-Mobile’s 110 million U.S. customers, this breach affected at least 37 million.


T-Mobile has revealed to the public that stolen data includes name, billing address, email, phone number, date of birth, T-Mobile account number and information such as the number of lines on the account and plan features of at least 37 million T-Mobile customers. As the investigation is ongoing, it may be revealed that additional information was accessed.


According to an interview, the hacker(s) carried out the data breach on or around Nov. 25, 2022, and so far those responsible remain unidentified. The stolen information was obtained through a single Application Programming Interface, T-Mobile said. Following the breach of customer data affecting nearly 40 million of its users, T-Mobile took more than a month to announce the breach and has yet to individually notify each affected customer as many state laws require.


T-Mobile customers whose data was stolen in the 2022 T-Mobile data breach must now take steps to protect themselves and mitigate the damages caused by the data breach. According to reports, identity theft is the most common consequence of a data breach and happens to about 65% of data breach victims. Consumers lost more than $56 billion to identity theft and fraud in 2020 alone, and over 75% of identity theft victims reported emotional distress.

Because T-Mobile did not protect its data properly, victims of the November 2022 T-Mobile data breach will be forced to take all steps possible to mitigate damages caused by the breach. Those whose data was compromised will likely face out-of-pocket costs for obtaining credit reports, credit freezes, credit monitoring services and other protective measures to deter and detect identity theft.


T-Mobile promised customers privacy and protection, yet the personal information of tens of millions of customers was compromised, putting them at high risk for identity theft and ongoing fear of financial and personal anguish. Hagens Berman believes that consumers deserve swift and just action from T-Mobile’s negligence in letting its customers’ data be stolen. The firm will investigate T-Mobile for negligence and violations of state consumer protection laws and seeks to secure financial relief for the many consumers impacted by the breach.

There is no cost or fee whatsoever involved in joining this action. In the event Hagens Berman or any other firm obtains a settlement that provides benefits to class members, the court will decide a reasonable fee to be awarded to the class's legal team. In no case will any class member ever be asked to pay any out-of-pocket sum.
