Mexican billionaire Carlos Slim Helú has asked the government to review the deadline for mandatory mobile phone line registration linked to the CURP [1].

The request highlights a potential crisis in connectivity for millions of Mexicans if the government does not extend the current timeframe. Because a vast majority of the market relies on prepaid services, a rigid deadline could lead to widespread service disruptions for the country's most vulnerable populations.

The mandatory registration process began on Jan. 9, 2026 [3]. Under the initiative pushed by President Claudia Sheinbaum, users must link their telephone lines to their Unique Population Registry Code, known as the CURP [1]. However, the current deadline for this process is set for June 30, 2026 [4].

Slim said the process is too complicated and the window for registration was too short, particularly for those using prepaid plans [2]. He said the government should re-examine the requirements to improve efficacy and ensure the system is convenient for citizens.

"Lo del registro es algo muy complicado… Deberían de darle una estudiadita," Slim said [5].

Data suggests the registration effort is struggling to gain traction. As of May 8, 2026, approximately 82.5% of lines remained unregistered [6]. This figure was recorded 53 days before the June 30 deadline [6].

Slim said that the registration process is very complicated and the timeframe for registering mobile lines was short, especially for prepaid users [2]. He said the administration should give the mandatory registration a "reestudiadita" to make it more effective [1].

The billionaire businessman said that the current complexity of the system may prevent a significant portion of the population from complying with the law before the end of June.

“"Lo del registro es algo muy complicado… Deberían de darle una estudiadita."”

The tension between national security efforts to track mobile lines and the practicalities of Mexico's prepaid-heavy market creates a significant risk of mass service disconnection. If the government adheres to the June 30 deadline despite the low registration rate, it could trigger a socioeconomic shock by cutting off communication for over 80% of the mobile user base.
