Overview
- Telcel said it will cut calls, texts, and data on unlinked numbers starting July 1 under the CRT mandate, with service limited to emergency and customer support lines until users register.
- The registration window runs from January 9 to June 30, 2026, and it covers every active SIM that can make calls, send SMS, or use internet service, while SIMs without those functions are exempt.
- Carriers have opened online and in‑person sign‑up channels, and Telcel’s portal asks for an official ID photo and a live selfie to confirm who holds the line.
- The CRT reports about 48 million mobile lines already linked, a tally that still leaves many numbers at risk of suspension after the June 30 cutoff.
- Users report AT&T México has auto‑linked some prepaid lines to past customer CURP records, raising privacy questions and prompting advice to check status in official apps before the deadline.
