Overview
- The staggered calendar starts with numbers ending in 0, which must be linked by 15 August 2026 and will receive a final 72‑hour grace message before carriers may suspend service.
- The CRT reports 69,666,315 lines registered — about 48.18% of roughly 144.6 million — leaving roughly 51–52% of lines unlinked and subject to upcoming suspensions.
- When a line is suspended callers keep access only to emergency and official alerts such as 911 and seismic warnings while normal calls, SMS and mobile data are disabled until the user completes verification.
- Carriers run the registration process and offer online or in‑person options that require an official ID and CURP or RFC plus a live selfie for biometric proof; Telcel allows up to three remote attempts and third parties like DiDi and OXXO are sending user alerts.
- The linkage drive has already trimmed millions of prepaid lines and raised average revenue per user, and prolonged suspensions risk disrupting bank and app access that use SMS authentication and could lead carriers to retire or reassign numbers.
