Major US Carriers Boost SIM Swapping Protections
SIM swapping attacks, where scammers transfer victims' phone numbers to their own devices, have prompted major US carriers like AT&T, T-Mobile, and Verizon to enhance account protection measures. These new tools can help safeguard personal accounts from unauthorized access by requiring additional verification steps or blocking number transfers altogether. For instance, AT&T's Wireless Account Lock prevents any changes to billing information without explicit user approval. Similarly, T-Mobile’s SIM Protection requires users to confirm their identity before allowing SIM card swaps. Verizon offers both SIM Protection and Number Lock features on its website and mobile app, adding an extra layer of security by requiring passkeys or voice verification for sensitive actions.
