Mobile coverage guide for Mexico

Mexico is an increasingly popular long-haul destination for Australians, from the ruins of the Yucatan and the beaches of Cancun and Tulum to the colonial cities of Oaxaca, San Miguel de Allende, and Mexico City's food scene.

Telcel and AT&T Mexico provide 4G and 5G coverage across major cities and tourist routes. Remote areas of Oaxaca's Sierra Norte and parts of the Copper Canyon can be off-grid. A HelloRoam eSIM gets you connected at Cancun International or Benito Juarez Airport in Mexico City.

eSIM Travel Tips for Mexico

The Yucatan Peninsula and ruins
Chichen Itza, Tulum, Coba, and Uxmal all have reasonable coverage near the visitor centres. The approach roads and jungle trails can be patchy. Download offline maps and site entry information before visiting Mayan ruins, particularly for self-guided early morning visits.
Mexico City food scene navigation
Mexico City has one of the world's great food cultures. Finding the best tacos al pastor, mole, and mezcal bars requires local food apps, Google Maps, and Instagram saves. Your HelloRoam eSIM keeps navigation running across the vast and complex city layout.
Uber in Mexican cities
Uber is available and widely used in Mexico City, Guadalajara, and other major cities. It is the safest transport option for tourists unfamiliar with local taxi pricing. A live data connection is essential for Uber. In Cancun's hotel zone, authorised taxis are also reliable.
Time zones across Mexico
Mexico spans three time zones. Mexico City is 15 to 17 hours behind Sydney depending on daylight saving. The Yucatan uses a different zone from the Pacific coast. Plan video calls home carefully and check which time zone your next destination observes.
Smart Traveller for Mexico
Check smartraveller.gov.au before visiting Mexico. Some regions outside major tourist areas have elevated safety concerns. The main tourist destinations including Mexico City, Oaxaca, Cancun, the Yucatan, and Baja California are generally safe for Australian tourists with standard precautions.

Mobile networks in Mexico: Telcel and AT&T Mexico

Mexico's two main carriers are Telcel (the largest with the widest rural coverage, owned by Carlos Slim's America Movil) and AT&T Mexico (strong in cities and northern regions). Telcel has the best coverage along the Pacific coast, the Yucatan, and in rural southern states. AT&T Mexico is competitive in major cities. Both offer 4G broadly with 5G in Mexico City and Guadalajara. Your HelloRoam eSIM connects to the strongest available network.

AT&T: 5G

Best time to visit Mexico from Australia

Mexico's best travel season varies by region. The Yucatan and Cancun are excellent from November to April, with the dry season and clear Caribbean water. Mexico City is pleasant year-round with a mild climate. The Pacific coast from Puerto Escondido to Puerto Vallarta is best from November to May. Hurricane season in the Caribbean runs from June to November, making October-November the risky tail end of the season for Yucatan beach holidays. The Australian winter school holidays in July fall in Mexico's wet season but still offer good beach weather.
