Buying a SIM Card at Mexico City Airport (MEX) in 2026

Are you flying to Mexico City and wondering if you can buy a prepaid SIM card at Mexico City Airport? I recently arrived at Mexico City International Airport and explored the tourist SIM card options myself, including AT&T, Movistar and Telcel.

The short answer is: yes, you can buy a SIM card at Mexico City Airport, but it is not the easiest or most convenient place to get connected. There are some options inside the airport, mostly through convenience stores and small phone shops, but the setup can be confusing if you have to do it yourself.

My recommendation is very clear: if you want to buy a local prepaid SIM card in Mexico, focus on Telcel. AT&T and Movistar can be cheaper, but Telcel has by far the best mobile network in Mexico. For tourists, especially those traveling beyond Mexico City, Telcel is the safest choice.

During my recent visit to Mexico City Airport I checked the SIM card options myself. I eventually bought a Telcel prepaid SIM card from a 7-Eleven inside the airport and managed to activate it, but I speak Spanish and I am very used to buying and setting up SIM cards around the world. For most tourists, this process is not super easy.

In this guide I will show you exactly where to buy a SIM card at Mexico City Airport, which shops sell Telcel, AT&T and Movistar SIM cards, what the opening times are, how much prepaid SIM cards cost and whether it is better to use an eSIM for Mexico instead.

Can you buy a SIM card at Mexico City Airport?

Yes, you can buy a prepaid SIM card at Mexico City Airport, but it is not as straightforward as many travelers expect. There are SIM card options inside the airport, but the choice is limited and the easiest option depends a lot on your arrival time.

But whenever you buy a prepaid SIM card at Mexico City make sure it is a Telcel SIM card, because it is the best prepaid SIM card for Mexico.

That said, buying a Telcel SIM card at the airport is not always beginner-friendly. If the official Telcel store is open, that is the easiest local SIM card option. If you buy from a convenience store, setup can be more complicated.

If you only need mobile data, an Airalo eSIM for Mexico is much easier because you can install it before your flight and arrive connected immediately.

Where to buy a SIM card at Mexico City Airport

Mexico City Airport is fairly easy to navigate. The arrivals area is basically one long hall with different exits called Puertas, or doors, numbered from 1 to 10.

Most SIM card options are located around these doors in small phone shops or convenience stores.

These are the main places where you can buy a SIM card at Mexico City Airport:

The best place to buy a SIM card at Mexico City Airport is the official Telcel store near Puerta 5 on the second floor, but only if it is open by the time you arrive. The big advantage of buying from the official Telcel store is that staff can help you choose the right prepaid package, activate the SIM card and check if mobile data works before you leave.

If the Telcel store is closed, convenience stores like OXXO and 7-Eleven are the next best option for buying a Telcel SIM card. However, this is not as easy as buying from an official store.

I personally bought a Telcel SIM card at the 7-Eleven at Mexico City Airport. It worked, but I speak Spanish and I am very used to buying and activating SIM cards around the world, so I managed to figure it out.

You need to buy the SIM card, find your new Mexican phone number, add credit and then activate the right prepaid package. Some steps require short dial codes and the menus are in Spanish. It is possible, but not as straightforward as walking into an official Telcel store where staff can help you set everything up.

Therefore, my advice is simple: if the official Telcel store is open, go there. If it is closed and you are comfortable setting up a SIM card yourself, buy a Telcel SIM card from OXXO or 7-Eleven.

If you only need mobile data and want to avoid the airport SIM card hassle completely, order an Airalo eSIM for Mexico before your trip.

Mexico City Airport SIM card prices

SIM card prices at Mexico City Airport depend on where you buy your SIM card and which provider you choose. Since Telcel is the only prepaid SIM card I recommend for tourists in Mexico, I would use Telcel prepaid plans as the main price reference.

These are good Telcel prepaid package examples for travelers:

Telcel prepaid plans usually include unlimited calls and SMS in Mexico, plus unlimited use of selected social media and messaging apps. However, this does not mean unlimited internet. TikTok and YouTube are not included in the unlimited social media allowance.

Some Oxxo stores and the 7-Eleven store offer slightly different Telcel prepaid SIM cards for tourists.

Best prepaid SIM card at Mexico City Airport

The best prepaid SIM card at Mexico City Airport is Telcel. It is not necessarily the cheapest option, but it is the only local SIM card I would seriously recommend for tourists arriving in Mexico.

At the airport you can also find AT&T SIM cards at MOBO shops, and they may be cheaper. However, AT&T does not have the same nationwide coverage as Telcel. If you only stay in Mexico City, AT&T can work fine, but most travelers arriving at Mexico City Airport continue traveling around Mexico sooner or later.

That is why I would focus on Telcel. Whether you travel to Oaxaca, Puebla, San Miguel de Allende, Guadalajara, Chiapas, the Yucatan Peninsula or anywhere else in Mexico, Telcel is the safer network choice.

If the official Telcel store is open, buy your SIM card there and ask the staff to activate the prepaid package for you. If the store is closed and you buy a Telcel SIM card from OXXO or 7-Eleven, make sure you understand that you may need to add credit and activate the package yourself.

Best eSIM for Mexico City Airport

If you only need mobile data, then an eSIM is the easiest way to get connected when arriving at Mexico City Airport. You can order it online, install it before your flight and use mobile data as soon as the plane lands in Mexico.

My recommended eSIM for Mexico City Airport is an Airalo eSIM for Mexico. Airalo uses the Telcel network in Mexico, which is the main reason why I recommend it. Telcel has the best mobile network coverage in Mexico and is the safest choice if you are traveling beyond Mexico City.

A local Telcel prepaid SIM card is still useful if you need a Mexican phone number, local calls, SMS or local top-up options. But if you only need data for Google Maps, WhatsApp, Uber, hotel communication, browsing and travel apps, an eSIM is much easier.

Buying a SIM card in Mexico City instead of the airport

If you have time, buying a SIM card in Mexico City instead of at the airport is usually the better option. At the airport the choice is limited, opening times matter and convenience store SIM cards can be a little annoying to set up.

In Mexico City you can simply go to an official Telcel store. That is the easiest option if you want a local prepaid SIM card, because the staff can help you choose the right package, activate the SIM card and check that mobile data works before you leave.

This is especially useful if you do not speak Spanish or if you are not used to activating prepaid SIM cards yourself. Buying a SIM card from OXXO or 7-Eleven at the airport is possible, but an official Telcel store in the city is much more straightforward.

How to get from Mexico City Airport to the city

Once you are connected, getting from Mexico City Airport to your hotel is easy. For most tourists, the simplest option is using a ride-hailing app like Uber. It is usually affordable, convenient and much easier than figuring out public transport after a long flight.

Mexico City Airport also has free WiFi, so in theory you can use the airport WiFi to order an Uber or contact your hotel. However, I personally prefer having mobile data as soon as I land, especially in a big city like Mexico City.

Having data immediately is useful for checking your hotel address, messaging your accommodation, following the route on Google Maps, translating messages, comparing transport options and staying connected if anything changes after arrival.

Final thoughts on buying a SIM card at Mexico City Airport

Buying a SIM card at Mexico City Airport is possible, but it is not as easy as it should be for such a major international airport. There are SIM card options, but the choice is limited and the best local option depends on your arrival time.

If the official Telcel store near Puerta 5 on the second floor is open, that is the best place to buy a prepaid SIM card at Mexico City Airport. Telcel is the mobile operator I recommend for Mexico because it has the strongest network across the country.

If the Telcel store is closed, you can buy Telcel SIM cards at some convenience stores like OXXO or 7-Eleven. I personally did this at the 7-Eleven at Mexico City Airport and it worked, but it was not super easy. I speak Spanish and I am very familiar with buying SIM cards around the world, so I managed to activate the package myself. For the average tourist, an official Telcel store is much easier.

AT&T SIM cards are also available at MOBO shops in the airport and can be cheaper, but I would not choose AT&T over Telcel if you are traveling around Mexico. The weaker network coverage is the trade-off, and for me Telcel is worth the extra cost.

Mexico City is often just the starting point of a bigger Mexico trip. If you are still planning your route, check out my guide with the best places to visit in Mexico. It also shows why choosing the right mobile network matters once you travel beyond the capital.

If you only need mobile data, an eSIM for Mexico is the easiest option. You can install it before your flight, skip the airport SIM card search and be connected as soon as you land. That is especially useful when using Uber, Google Maps, WhatsApp or contacting your hotel after arrival.

If you prefer buying a local SIM card after arrival, consider waiting until you are in the city and go to an official Telcel store.
