Miami, FL — Data Breach Law Group is investigating a data breach involving T-Mobile, reported to the Indiana Attorney General on August 29, 2025. The firm is reviewing whether affected individuals have legal claims arising from the incident.

T-Mobile is a major telecommunications and technology company that provides wireless voice and data services to millions of consumers. As a mobile network operator, the company typically collects and maintains extensive personal data, including customer names, billing addresses, Social Security numbers, government-issued identification, and detailed account service information. In 2025, T-Mobile officially reported a data security incident to the Indiana Attorney General, confirming that unauthorized parties may have accessed sensitive customer records. If you have received a formal data breach notification letter from the company, it indicates that your personal information was likely included in the compromised data set. This notice serves to inform you of the incident and provide guidance on the steps you should take to protect your identity and financial security.
