Current regulations stipulate that lines failing to complete the Unique Population Registry Code (CURP) registration by the end of the legal deadline will enter a state of suspension.
There is uncertainty regarding exactly which mobile phone functions will stop operating once the June 30, 2026, deadline is reached. Based on the technical guidelines of the Telecommunications Regulatory Commission (CRT), we detail the operational landscape below.
Services that will be restricted#
Starting at 00:00 hours on July 1, 2026, operators will proceed with the technical suspension of unidentified lines. This implies the deactivation of the following services:
- Outgoing and Incoming Voice Traffic: Conventional phone calls cannot be made or received.
- Mobile Data Service: Internet connection through the operator’s 4G and 5G networks will be disabled.
- SMS Messaging: The sending and receiving of short text messages (essential for bank authentication tokens) will be suspended.
Operational exceptions (Emergency Services)#
Even in a state of suspension, the regulation mandates keeping certain basic functions active for public safety reasons:
- Calls to 911: All devices, with or without registration, will maintain the ability to connect calls to national emergency services.
- Access to registration portals: Web traffic to the operators’ microsites dedicated exclusively to line regularization will remain open free of charge (sponsored browsing), allowing the user to complete the delayed process using their own suspended mobile data.
Is the phone number lost immediately?#
According to the CRT Data Report, lines will not be permanently canceled on the first day. There will be a grace period of 90 calendar days following June 30.
- During the grace period: The user can reactivate their same line by linking their CURP at any time.
- At the end of the grace period: If the line remains unregistered after the 90 days, the number will be released for subsequent reassignment by the operator, and the user will lose ownership of it.
