Protecting Your Identity by Thwarting SIM Swap Attacks: A Guide for a Digitally Dominated Future

In the year 2025, a cell phone number no longer represents just a communication line. It is the gateway to the online world, central to signing up for an array of Internet services - from retail to banking, and social media to healthcare. However, with the increased usability comes inherent risks. If someone steals your phone number, they potentially assume your digital identity, thus paving the way for hackers to access your online accounts. In an effort to circumvent this, it’s essential to guard your number proactively against SIM swapping, a cyberattack where the attacker snatches the victim’s number under false pretenses. It’s a world where malicious hackers impersonate customers to cell carriers using gleaned, public data - exploiting the lack of stringent checks on customer consent. But despair not, with the rise in incidence, heightened security measures make it harder for your digital avatar to be stolen. Leading phone providers such as AT&T, T-Mobile, and Verizon have taken bold steps towards fortifying phone number security. Now, it’s up to the users to enable these features, often shadowed in the obscure corners of the carrier’s account settings. The shining armor, ‘Wireless Account Lock,’ introduced in July by AT&T allows customers to prevent SIM swaps by inhibiting movement of the phone number to other devices or accounts. Similarly, T-Mobile allows customers to block unauthorized number port-outs for free. Not to be left behind, Verizon has raised the bar with not one but two security features - SIM Protection and Number Lock. The latter’s off-switch triggers a 15-minute delay before any transactions can proceed, allowing the actual account holder to step in and halt malicious account changes.
