Phone rules in Mexico
The rules a caller, a visitor or a new resident runs into in Mexico, each with its source.
| ID to buy a SIM | Since 9 January 2026 every mobile line must be linked to an identified holder under the CRT 'Lineamientos para la identificación de líneas telefónicas móviles'; a new SIM only allows emergency calls until it is linked, and an individual may link at most 10 lines. Mexicans register with their CURP plus an official ID (INE voter card, passport or national ID card); foreigners, including tourists who buy a Mexican SIM or eSIM, use a valid passport or a temporary CURP for foreigners, while visitors on international roaming are not covered yet (the CRT will define a mechanism after the 2026 World Cup). Existing prepaid lines not yet linked are suspended to emergency-only service on a staggered CRT calendar running from 15 August to 31 December 2026 according to the number's last digit.dof.gob.mx · gob.mx |
|---|---|
| Monthly contract | Telcel postpaid requires a valid official ID, proof of address, authorisation to check the credit bureau (Buró de Crédito), consent to a possible address-verification visit, at least two personal references, a guarantee (fianza) and signature of the adhesion contract. Under the CRT line-identification rules a foreigner's line is linked with a passport or a temporary CURP for foreigners.telcel.com · dof.gob.mx |
| Calling apps | None known. Article 132 of the 2025 Telecommunications and Broadcasting Law (LMTR) requires internet access providers to deliver the contracted capacity, speed and quality regardless of content, origin, destination, terminal or application; no restriction on WhatsApp, FaceTime or Skype calls was found.dof.gob.mx |
