T-Mobile US and its unit Metro PCS informed customers Thursday about a potential security breach that was discovered and shut down by the company.
The cybersecurity team found and shut down unauthorized access to certain information on Aug. 20, and reported the matter to authorities, T-Mobile said in a statement on its website.
No financial data, social security numbers or passwords were compromised, but other personal information like name, email-id, phone number, zip code, account number or type (postpaid or prepaid) may have been exposed, the company said.
About 3 percent of T-mobile’s 77 million customers could have been affected, a company spokesperson told technology news website Motherboard.
T-Mobile did not respond to Reuters request for comment outside regular business hours.
