eSIM Mexico

eSIM Mexico: prepaid data on AT&T Mexico, from Cancún to Mexico City

Whether you land at Cancún for the Riviera Maya or fly into Mexico City for tacos, museums and a side trip to Oaxaca, an eSIM Mexico means your phone is online before you reach the taxi rank. Skip the airport SIM kiosks and the daily roaming pass from your home carrier: buy the Mexico eSIM online, scan the QR code at home, and it attaches to AT&T Mexico automatically when you arrive. Your own SIM stays active, so your number and WhatsApp keep working exactly as they do at home.

Networks and coverage in Mexico

The plan runs on AT&T Mexico, one of the country’s national operators. Coverage is strong in Mexico City, Guadalajara, Monterrey, Cancún, Playa del Carmen, Tulum and Puerto Vallarta, and along the main toll highways that connect them. Deep in the Yucatán jungle, in the highlands of Chiapas or on the Copper Canyon route, signal thins out as it does on every network, so treat remote stretches as offline time and save your maps in advance. Inside resorts the eSIM works alongside the property Wi-Fi rather than replacing it, which is useful when the pool bar has no signal but the beach does.

Plans, prices and validity

A Mexico eSIM prepaid data plan starts from $4 for 1GB, with 2GB, 3GB, 5GB, 10GB, 15GB and 20GB options above it. Validity follows the size: 1GB lasts 7 days, 2GB 10 days, 3GB 14 days, 5GB 21 days, and 10GB, 15GB and 20GB each run for 30 days. A long weekend in Cancún with maps, ride-hailing and photo uploads fits comfortably in 2GB or 3GB. A two-week loop through Mexico City, Oaxaca and the Pacific coast is more relaxed at 5GB to 10GB, and anyone working remotely from a beach town or tethering a laptop should go straight to 15GB or 20GB. The validity clock only starts the first time your phone connects to AT&T Mexico, so installing a week early costs nothing.

Tips for mobile data in Mexico

Ride-hailing apps are the easiest way to get around Mexico City and Guadalajara, and they need live data to work from the moment you step outside the terminal. Restaurants, tour operators and small hotels across Mexico confirm bookings by WhatsApp, so keeping your existing number reachable on your primary SIM matters. Long-distance buses between cities are comfortable but their onboard Wi-Fi is unreliable; download playlists and offline maps beforehand. Card payments are common in tourist areas, while markets and street food stalls run on cash, so a banking app that works on the move helps you find an ATM and check your balance.

Calls and a phone number

The Mexico eSIM is data-only by default. Add a voice bundle (+100, +200 or +300 minutes) and you receive a dedicated international phone number, US +1 or UK +44, for calls and SMS. That number is handy for calling a hotel in Tulum, confirming a cenote tour, reaching a car-rental desk at the airport or receiving verification codes from your bank, all without exposing your home number to roaming charges.

Installing your eSIM for Mexico

• Order online and the QR code arrives by email within minutes; nothing is shipped.
• Scan it over Wi-Fi before you fly, from the cellular or SIM settings on your phone.
• On landing, switch data roaming on for the eSIM line and select it for mobile data; your primary SIM keeps your own number.

• Top up from the GlobaleSIM dashboard or app whenever you need more, with 24/7 human support on WhatsApp.
