AT&T Enhances Security to Combat SIM Swap Fraud and Protect User Role
updated July 3, 2025
AT&T is implementing a new “wireless account lock” to prevent unauthorized changes to mobile accounts, addressing the growing threat of SIM swapping. This security enhancement aims to protect users from scammers who hijack accounts by illegally transferring phone numbers.
SIM swapping, also known as port-out fraud, has plagued wireless carriers for years. Federal prosecutors reported last year that one SIM swap scheme alone resulted in $400 million in stolen cryptocurrency. Dozens of victims who used their phones for two-factor authentication to access cryptocurrency wallets were affected.
T-Mobile experienced a similar breach in 2022, where unauthorized access to a management platform used by subscription resellers occurred. The breach involved a SIM swap of a T-Mobile employee, a phishing attack, and at least one other compromise.
These attacks, which have been ongoing for over a decade, gained traction with the rise of Bitcoin and other cryptocurrencies. Scammers sometimes impersonate account holders or bribe carrier employees to make unauthorized account changes, assuming the victim’s role.
What’s next
AT&T’s new security measures represent an effort to stay ahead of evolving fraud tactics and protect customers from financial losses and identity theft. Other carriers are expected to follow suit with similar protections.
