Anonymous prepaid SIM cards are dying in Mexico. By July 1, 2026, every active cell phone number in the country must be biometrically linked to a named, government-credentialed individual or face suspension. That’s around 127 million numbers, each one tethered to an identity the Mexican government can look up by name.
The mobile registration law took effect January 9, 2026, covering prepaid and postpaid plans, physical SIMs, and eSIMs alike. Existing subscribers have until June 30 to complete registration. New lines activated after January 9 get 30 days. Miss the window, and the line goes dark.
The enforcement mechanism runs through the CURP Biométrica, Mexico’s biometric upgrade to its existing population registry code. The new credential embeds a photograph, electronic signature, and QR code that ties directly to biometrically verified records held in the national registry.
Residents registering a mobile line must provide their CURP number alongside a valid government ID, which makes biometric enrollment not optional but structurally required. You cannot register a phone number without first handing your biometric data to the state.
What Mexico is building here is a national phone network where every number has a face attached to it.
