NEW YORK — T-Mobile has agreed to pay $350 million to customers affected by a class action lawsuit filed after the company disclosed last August that personal data like social security numbers had been stolen in a cyberattack.
In a Securities and Exchange Commission filing on Friday, the mobile phone company said the funds would pay for claims by class members, the legal fees of plaintiffs’ counsel and the costs of administering the settlement. It also said it would spend $150 million next year and in 2023 to fortify its data security and other technologies.
Nearly 80 million U.S. residents were affected by the breach. In addition to Social Security numbers, other information breached included names and information from driver’s licenses or other identification.
T-Mobile, based in Bellevue, Washington, became one of the country’s largest cellphone service carriers, along with AT&T and Verizon, after acquiring rival Sprint in 2020. It reported having a total of 102.1 million U.S. customers after the merger.
