Due to the 2026 FIFA World Cup, Mexico will receive a high volume of international visitors during June and July.
Since the deadline for the mandatory registration of mobile lines ends on June 30, 2026, it is important for visitors to know how their telecommunications services will operate within the national territory.
Users with International Roaming (Foreign Lines)#
If you visit Mexico and use the SIM card from your home country (e.g., customers of T-Mobile, AT&T US, Verizon, Vodafone, etc.), your service will operate via International Roaming.
- No registration required: Foreign lines on roaming are not subject to the linking requirement in Mexico.
- Uninterrupted service: You can make calls, send messages, and use mobile data according to the international fair use policies of your original provider.
Users Acquiring a Local Mexican SIM#
If during your stay in Mexico you decide to buy a SIM card from a local operator (Telcel, AT&T Mexico, Movistar, Bait, etc.) to avoid roaming charges, you must comply with the registration regulations.
Requirements for Foreigners#
Official regulations establish exceptions for those who do not have a Unique Population Registry Code (CURP). To activate and maintain a local line, you must provide:
- Valid passport from your country of origin.
- Validation photograph (proof of life) at the time of registration on the operator’s portal or in person.
- Optional: If you have temporary or permanent legal residence, you can use your CURP for foreigners.
