T-Mobile has had several data breaches. The most significant was a data breach in August 2021. The cyberattack compromised the data of 47 million customers, former customers, and those who had applied for credit with the mobile telecom company. While the breach did not expose customers’ payment information, the hackers accessed customers' social security numbers, names, birthdays, and driver’s license numbers. T-Mobile alerted the affected customers and provided identity protection services, scam-blocking protection, and Account Takeover Protection.
