T-Mobile said that the attackers stole the information of around 37 million postpaid and prepaid users before the company detected and fixed the problem. The airline stated at the time that no passwords, financial information, or social security numbers were obtained. Google Fi confirms the same, adding that no PINs or text message/call data were stolen. Only phone numbers, account statuses, SMS card serial numbers, and certain service plan information, such as international roaming, seemed to be accessible to the hackers.
