Mexico operates three major mobile network operators. Telcel controls approximately 65 percent of the market as of 2024, AT&T Mexico holds roughly 20 percent, and Movistar maintains approximately 12 percent. Telcel, owned by América Móvil, operates the most extensive network infrastructure, reaching approximately 98 percent geographic coverage across Mexico's 1.96 million square kilometers. AT&T Mexico, which acquired Iusacell and Nextel Mexico in 2015, has invested over 7 billion USD in network expansion between 2015 and 2023. Movistar, operated by Telefónica, focuses primarily on urban centers and tourist corridors. The Instituto Federal de Telecomunicaciones regulates all telecommunications services and enforces coverage requirements and consumer protection standards.
4G LTE networks cover approximately 92 percent of Mexico's population as of 2024, with 5G deployment concentrated in Mexico City, Guadalajara, Monterrey, Querétaro, Puebla, and tourist zones including Cancún, Playa del Carmen, and Puerto Vallarta. Telcel began 5G deployment in 2021, with approximately 60 cities having partial 5G coverage by early 2024. AT&T Mexico launched 5G services in 18 cities in 2022. Download speeds on 4G LTE networks average 20-35 Mbps in urban areas and 8-15 Mbps in rural zones. 5G networks deliver 100-400 Mbps in covered areas. 3G networks remain active across approximately 99 percent of populated areas, providing fallback connectivity where 4G infrastructure does not reach.
Foreign visitors purchase prepaid SIM cards without presenting tourist visas or special documentation. Mexican law requires registration of all SIM cards with official government identification. Passport presentation is mandatory at purchase. Retailers scan the passport biographic page and record the document number, full name, and nationality in the National Mobile Users Registry, administered by the Instituto Federal de Telecomunicaciones since 2012. This registration process takes 3-8 minutes. SIM cards activate within 10 minutes to 2 hours after purchase and registration. Cards not registered within 24 hours of purchase become deactivated under telecommunications regulations enforced since 2021.
Telcel SIM cards are sold at approximately 18,000 retail locations including Telcel-branded stores, OXXO convenience stores, 7-Eleven locations, Sanborns department stores, Walmart Supercenter outlets, and authorized resellers displaying Telcel signage. AT&T Mexico maintains approximately 1,100 company-owned stores and sells through approximately 8,000 authorized retailers. Movistar operates approximately 600 branded stores and sells through approximately 4,000 partner locations. OXXO stores, with over 21,000 locations across Mexico as of 2024, sell prepaid SIM cards and top-up credit for all three carriers. Airport kiosks in Mexico City International Airport Terminal 1 and Terminal 2, Cancún International Airport terminals 2, 3, and 4, Guadalajara International Airport, and Monterrey International Airport sell SIM cards at prices typically 15-30 percent above street retail rates.

All carriers charge per-megabyte rates of 0.10-0.50 pesos when purchasing data without package plans.
Recharge credit, called "recargas," is purchased at the same retail locations selling SIM cards. OXXO stores process recharges by scanning a barcode or entering a phone number at checkout. Minimum recharge amounts are 20 pesos for Telcel and AT&T, 30 pesos for Movistar. Maximum single recharge amounts are 1,000 pesos. Recharges can also be purchased through carrier mobile applications, online portals, or by dialing *133# for Telcel, *111# for AT&T, and *555# for Movistar and following voice prompts. Credit validity ranges from 10 days for 20-peso recharges to 365 days for recharges of 500 pesos or more. Unused credit expires after the validity period unless additional recharges extend the expiration date.
Coverage along major highways connecting Mexico City, Guadalajara, Monterrey, and Querétaro maintains continuous 4G LTE signal on Telcel and AT&T networks. Federal Highway 15D from Nogales to Guadalajara, Highway 85D from Monterrey to Mexico City, and Highway 150D from Mexico City to Veracruz show consistent 4G coverage with occasional drops to 3G in mountainous sections through the Sierra Madre Oriental. The Yucatán Peninsula maintains strong 4G coverage on Federal Highway 180 connecting Cancún, Playa del Carmen, Tulum, and Mérida, with Telcel providing the most consistent signal. Highway 307 along the Caribbean coast from Cancún to the Belize border shows continuous coverage in populated areas with signal gaps in the Sian Ka'an Biosphere Reserve section spanning approximately 80 kilometers.
Rural coverage varies significantly by region and carrier. The Sierra Madre Occidental mountain range shows intermittent coverage, with many villages relying on 3G or 2G signals. Copper Canyon areas serviced by the Ferrocarril Chihuahua al Pacífico train route have limited coverage, with signal availability primarily at major stops including Creel, Divisadero, and Bahuichivo. Telcel maintains 3G coverage in most towns with populations exceeding 1,000 residents. Remote areas of Chihuahua, Durango, and Oaxaca states show coverage gaps spanning 20-100 kilometers between signal zones. The Baja California Peninsula has 4G coverage along Highway 1 from Tijuana to Cabo San Lucas, with signal gaps in desert sections and intermittent coverage on side roads leading to smaller towns and beaches.
Tourist destinations maintain strong coverage. Cancún, Playa del Carmen, Tulum, Puerto Vallarta, Los Cabos, and Acapulco have comprehensive 4G LTE coverage from all three carriers. Archaeological sites including Teotihuacán, Chichén Itzá, Tulum ruins, Palenque, Monte Albán, and Uxmal have 4G coverage from Telcel, with AT&T and Movistar providing coverage at major sites. Smaller ruins including Calakmul, Ek Balam, and Yaxchilán show limited or no coverage. The Monarch Butterfly Biosphere Reserve areas near Angangueo and Ocampo in Michoacán state have 3G coverage in towns with no signal in forested sanctuary zones. Cenotes near Tulum including Dos Ojos and Gran Cenote have no mobile coverage due to underground locations and remote access roads.
WiFi availability in Mexico is widespread in urban areas and tourist zones. Most hotels in cities and resort areas provide WiFi as standard amenity. Coffee shops including Starbucks, which operates over 850 locations in Mexico, and Italian Coffee Company, with approximately 200 locations, offer free WiFi requiring email registration or social media login. Sanborns restaurant chains and Vips restaurant locations provide free WiFi to customers. Shopping centers in Mexico City, Guadalajara, Monterrey, and Querétaro offer free public WiFi in common areas. Plaza Carso, Antara Fashion Hall, and Artz Pedregal in Mexico City provide WiFi without registration. Internet cafés, called "cibercafés," operate in most cities charging 10-25 pesos per hour, though their numbers have declined approximately 60 percent since 2015 due to increased smartphone penetration.
Public WiFi networks in Mexico City include "Red Puebla WiFi" covering Zócalo and surrounding historic center areas, and "Red CDMX" operating in parks, plazas, and government buildings across the capital. Guadalajara operates "WiFi GDL Gratis" in downtown areas and major parks. Puebla provides "Red Puebla WiFi" in the historic center and Zona Angelópolis commercial district. These networks require phone number registration and provide speeds of 2-8 Mbps.

SIM card expiration policies require attention from extended travelers. Telcel SIM cards with no activity for 60 consecutive days enter a suspended state requiring recharge to reactivate. After 120 days of no activity, the phone number becomes permanently deactivated and cannot be recovered. AT&T Mexico deactivates SIM cards after 90 days without recharge or usage. Movistar implements a 75-day policy. Maintaining an active number requires recharge before the expiration date even if the previous credit balance and validity period have not been exhausted. This allows preservation of the phone number for future visits.
Phone number portability between carriers is available under regulations implemented by the Instituto Federal de Telecomunicaciones. Customers can transfer their number from one carrier to another by requesting portability through the receiving carrier. The process completes within 24 hours for prepaid numbers and up to 3 business days for postpaid contracts. No fees are charged for number portability as of 2024. This service primarily benefits residents rather than short-term visitors but is available to all registered SIM card holders.
Postpaid contracts require Mexican government-issued identification or permanent residency documentation and are not accessible to tourists on visitor permits. Monthly postpaid plans from Telcel cost 300-1,500 pesos for packages including 5-40 GB data, unlimited domestic calls and texts, and varying international call allowances. AT&T postpaid plans cost 250-1,200 pesos monthly. Movistar plans cost 200-900 pesos. Contract plans require 12-24 month commitments and include subsidized phone purchases in many cases. Tourists and temporary visitors rely exclusively on prepaid options.
