Telco providers in Mexico

There are three main telco providers in Mexico: Telcel, Movistar and AT&T. All three operators go through a strict approval process before being allowed to operate, and each one competes with the others to offer the best deals. Their services have all been tried and tested by both locals and travelers, and can be trusted. According to OpenSignal’s country coverage map, Mexico has good coverage around the main towns and cities, but the farther out you head, the more unreliable the signal will become.

About Mexico’s telco providers

Mexico’s market leader is Telcel, followed by Movistar and AT&T. All three operators offer prepaid SIM cards, and you can buy them from supermarkets, kiosks, drug stores and official stores, as well as at the Mexico City and other international airports. 2G, 3G and 4G plans are available on all networks for unlocked GSM phones. You can buy a SIM card by showing your passport, and your telephone number is already active when you purchase it. To add credit, there are several prepaid card machines around various towns and cities, and vouchers are stocked in stores and supermarkets.

Below, we have broken down each telco provider to highlight exactly what they can offer you during your stay in Mexico.

Prepaid SIM cards are called “Amigo” and can be purchased for MXN149, which comes with MXN75 credit. Better voice and data plans can be purchased within packages. SIM cards come in all sizes, but some might have to be cut to fit the nano or micro slot in your phone.

Credit can be added in the following denominations: MXN20-MXN500, and each top-up amount is valid for six months from the time of upload. Make sure you only buy credit from the official websites or purchase credit vouchers with the official logo printed on them. Dial *133# to check your balance.

Some top tips from finder.com staff:

• Spanish is the official language in Mexico. If you don’t know any Spanish, consider downloading Google Translate onto your phone before you travel. Although some locals can speak English, many cannot.
• Locals call a SIM card a “SIM” or “chip”.
• Ask the retailers to set up the SIM for you. This will save you a lot of time and trouble, but it’s also helpful to cover anything you might not understand.
• Make sure you get to the stores early before the crowds.

TripAdvisor tips for the best SIM cards and where to buy them

TripAdvisor reviews can help guide you through which SIM cards have been tried and tested in Mexico.

Here are some top tips from TripAdvisor users:

• “I’ve had a Telcel SIM card that I’ve used for trips for the past 4 years. It’s been very reliable and the coverage has always been excellent. Also, their website is pretty easy to navigate even if you don’t know Spanish very well and I’ve never had a problem reloading the SIM with my foreign credit card.”
• “When you buy your SIM card and load money for a data and voice “Paquete” please note that data plans and voice plans are good for a designated period of time…14 days…30 days…etc. Order your card a few weeks before you need it and when you pay for your data plan make sure it goes into effect on the day you arrive in Mexico otherwise you will time out before the end of your trip.”
• “I bought an AT&T SIM card at the airport. Very inexpensive and it worked great for our 2 weeks in Mexico City even though I mostly used Wi-Fi for Uber and email”
