Overview
- Carriers hit the Jan. 8 deadline to enable management platforms and must now sell only disabled SIM cards that users activate through registration.
- The registration period runs Jan. 9 to June 1, 2026, with unlinked lines suspended starting July 1 and limited to emergency calls and designated alerts until users register late.
- Users can register remotely by uploading an official ID and completing a liveness selfie, with up to three online attempts before in‑person validation is required at service centers.
- Telcel says a consultation portal will launch Feb. 7 for people to check lines associated with their CURP or companies with their RFC and to manage unlinking if needed.
- Rules cap individuals at 10 numbers and require CURP for people and RFC for legal entities, while foreigners may use a valid passport or a temporary CURP.
