The Phone Number Trap: Why Your Most Trusted ID Is Also for Sale
Every week, thousands of people discover their phone number has quietly changed hands. One moment their phone shows full signal; the next, it shows nothing — no bars, no texts, no calls. By the time they notice, the person who now controls that number has often already used it to reset a password, receive a one-time code, and walk straight into a bank account. This is SIM swapping, and despite years of warnings, it keeps working for a reason that has little to do with hacking skill and everything to do with how the phone number itself is treated: as both a piece of tradeable data and a trusted proof of identity. Those two roles were never supposed to coexist, and the collision between them is now forcing regulators, carriers, and enterprises to rethink one of the most basic assumptions in digital security.
