Mexico is a land of paradoxes. On the one hand, it is one of the largest mobile markets in Latin America. On the other hand, the level of innovation penetration here comes with a noticeable delay. However, if the situation with eSIM is relatively favorable. The technology is not prohibited, operators are implementing it, and travelers have a real chance to do without going to offices and without fussing with microscopic trays for SIM cards.
eSIM technology in Mexico is officially operational and supported by major operators. It's convenient, but not always easy. Cities like Mexico City, Monterrey and Guadalajara make it easier to connect. In small towns and in the south of the state it is more difficult, especially if you are a traveler.
Mexico is not catching up, but is not falling behind. The issue with eSIM here rests not on technology, but on bureaucracy and the willingness of employees to serve foreigners without CURP - the Mexican identification code.
There are three major players in the Mexican mobile market: Telcel, AT&T and Movistar. They set the tone and form the general idea of how eSIM works here. Besides them, there are also smaller virtual operators, like Oui, Diri, Altán Redes, but they are more focused on the economical segment, and their eSIM is either still difficult or non-existent.
Mexican operators supporting eSIM nationwide:
- Telcel is the most powerful player, covering the entire country, including jungles, mountains, villages. But Mexico City Airport does not have an official Telcel office with eSIM support - only regular SIM cards.
- AT&T México is a strong urban operator. Good in Mexico City, in the north, in the states of Nuevo Leon, Coahuila, Bahia California. The AT&T México website has an eSIM registration option, but to complete the process you still need physical verification - either in the office or through courier delivery (which, of course, is not available to tourists). Plus AT&T is the ability to choose interesting packages: 3, 5, 10 GB, and in addition to this, unlimited for instant messengers like WhatsApp.
- Movistar México is the third largest, available in all states, but weaker in coverage. You can buy an eSIM in the official store by presenting your passport.
- Altán Redes (Red Compartida) is an infrastructure provider, MVNOs operate through it, in particular, Oui Movil, FreedomPop, Bait, PilloFon. Not everyone supports eSIM.
Geography and accessibility
Central Mexico (Mexico City, Toluca, Queretaro, Puebla)
Connecting eSIM is easier. There are offices of all three operators in all cities. A passport is usually sufficient for purchase. Representatives are more familiar with travelers. Telcel and AT&T issue an eSIM upon first purchase, without contract pressure.
North (Monterrey, Tijuana, Chihuahua, Torreon)
Similar situation. Operators, especially AT&T, are active, coverage is excellent. There are many guest countries from the USA, for this reason employees are often loyal. In Monterrey, you can connect eSIM directly at the airport at AT&T (official stand).
South and Southeast (Oaxaca, Chiapas, Yucatan, Quintana Roo)
More difficult. In Cancun it’s easier (there are a lot of foreigners). In Merida it’s a little worse, but tolerable. In Palenque or San Cristobal there is almost no possibility. There, the sellers themselves do not always know what eSIM is. Telcel has coverage everywhere. The rest are unstable.
West (Guadalajara, Colima, Nayarit)
The situation is like in the center. Many company offices. AT&T and Movistar offer eSIM. When visiting the power zones (Sayulita, Puerto Vallarta) - only Telcel works reliably.
Buying an eSIM by a foreigner
In theory, eSIM in Mexico is available to anyone with a document. In practice, a lot depends on the office and the employee.
Do you need a passport? Yes, almost always. To purchase an eSIM from a local operator, a passport is the minimum requirement. Sometimes you will need additional documentation, such as a driver's license or proof of residence, but in the case of a guest country, most often just showing your passport is enough. No Mexican numbers or CURP are required for prepaid plans. This is the law: a traveler has the right to buy a prepaid package without a local ID.
- In 80% of cases they will ask for a passport.
- CURP is rarely asked.
- Nobody imposes a contract, especially if you directly ask for a prepaid card «prepago con eSIM».
- It is not necessary to have a Mexican phone number; you can purchase an eSIM upon your first purchase.
- You can ask for a QR code to scan, but often the staff will scan it into your phone on the spot.
Where to buy
- Branded offices of Telcel, AT&T, Movistar are in cities in almost every shopping center.
- Offices at airports are best at AT&T, in Mexico City (including in terminals 1 and 2 of the airport) and Monterrey. Telcel rarely uses regular SIMs, most often.
- Online stores of operators do not work with foreigners without CURP.
- Marketplaces like MercadoLibre offer eSIM, but these are often intermediaries or scammers. Not worth it.
As for buying an eSIM at the airport, there is confusion and uncertainty. At the Benito Juarez International Airport in Mexico City there are counters of cellular operators, but often they are not always working, and the offers are focused on regular SIM cards. Installation of eSIM is offered either upon request or reluctantly.
Interestingly, some Mexican operators have begun experimenting with selling eSIMs through automated kiosks. Such terminals are installed in shopping centers, and they issue a QR code after verifying the passport through a scanner. But for now these are pilot projects, and there are no such kiosks at the airport. There are some in the center of Mexico City, but they are unstable.
International eSIM
For guest countries, the use of foreign eSIM — Often the easiest way to take care of communications in Mexico is before you arrive in the country. There are virtual operators on the market that use the infrastructure of large players. One of the most interesting is the company Airalo. It is an international platform that sells eSIMs with coverage in dozens of countries, including Mexico. A guest of the state can install an eSIM from Airalo or similar services (Nomad, Ubigi, Holafly, GigSky) before flying to Mexico City. It's simple and fast: purchase through a website or app, QR code, activation - and you're already online. But this simplicity comes at a price: these eSIMs are often more expensive and provide access to limited roaming rather than local rates. Let's say Airalo offers a Mexican eSIM with 1 GB for $9, 3 GB for $24, and 5 GB for $35 for 30 days. Coverage depends on which network you partner with. Usually this is Telcel or Movistar. In terms of speed and stability, such eSIMs are in no way inferior to local ones - when it comes to cities. In the mountains and rural areas - a minus, because the priority of the network is for local subscribers.
Many foreign eSIMs work in Mexico:
- Airalo
- Holafly
- Nomad
- Ubigi
- GigSky
Prices are higher, but registration takes 5 minutes:
- 1 GB – $9–10
- 3 GB – $22–26
- 5 GB – $30–35
- Unlimited (conditional, up to 20 GB) – $39–59
The nuance here is important. Mexico is a country where traffic priority goes to those who are their own. Relatively speaking, a Telcel SIM card purchased in an office and registered to a Mexican will issue a better signal than an eSIM installed through an international platform. This is confirmed by Internet speed tests in real conditions. Even with the same coverage, the difference can be significant - especially during peak hours. In Mexico City, this is especially noticeable in the metro, where Telcel is the only operator that provides sane connectivity, including eSIM, and international eSIMs often lose network or have sharply reduced speeds.

Advice
In cities, go to the AT&T corporate office. Usually faster and easier.
In rural areas, Telcel is better. Sometimes this is the only signal in the area.
If you have an iPhone without a SIM slot, get ready to go to the office and talk in Spanish.
In Cancun, Los Cabos, Mexico City - everything works. In Oaxaca or Chiapas it is unstable.
If you don’t want to waste time, install an eSIM from Airalo before your arrival and use it.
Is it even worth bothering with an eSIM if you are a traveler for 1-2 weeks? The question is open. On the one hand, it’s convenient: you don’t need to look for a paperclip, you don’t need to take out your main SIM card, everything is installed in a minute. On the other hand, with eSIM in Mexico there is still a lot of manual labor: going to the office, explanations, scanning documents, possible refusal. For this reason, if you have an iPhone or modern Android, eSIM is a good solution for 2-3 weeks, especially if you use an international platform. If you want full coverage and low prices, the old-fashioned SIM still rules.
If you are a guest of the state, want the Internet and don’t want complications - install an eSIM from Airalo, pay more, but get it in 5 minutes. If you are staying for a month and are willing to spend 30 minutes on a visit to the office, you can purchase the same eSIM from Telcel or AT&T for 200–300 pesos and use it for a month with full coverage. The decision depends on your goals and patience.
But no matter what you choose - a regular SIM, an eSIM from a local operator or a global service - Mexico City in 2025 is no longer a city where you can be left without communication. The main thing is not to trust kiosks at the airport, not to count on miracles during online activation, and remember: in Mexico, a lot depends not on the law, but on the specific person at the counter.
