Overview
- President Claudia Sheinbaum confirmed there will be no extension and that operators must suspend any mobile line not linked to a CURP on July 1, 2026, leaving those numbers able only to call emergency services and receive government alerts.
- The registration links each line to official ID and a biometric selfie or in‑person verification and limits individuals to 10 linked lines while companies face no per‑account cap.
- Operators and regulators say a very large share of Mexico's lines remain unregistered, with reports indicating more than 114 million lines pending, creating a need to register roughly a million lines per day to meet the deadline.
- Suspended lines will block SMS and mobile data, which will disrupt two‑factor authentication, banking apps, government services and messaging tools such as WhatsApp for affected users.
- Rollout problems and evasion methods have surfaced: operators reported server interruptions and alleged system vulnerabilities, investigators found pre‑activated SIMs sold in Mexico City's Centro Histórico for about 200 pesos, and reports say AI deepfakes have been used to bypass biometric checks.
