Mexico eSIM
The Mexico eSIM runs on the Telcel, AT&T and Movistar networks, comes with 1 to 20 GB, is prepaid with no contract and no registration, and is online the moment you land in Cancún.
Your Selection
Your plan only starts counting when the eSIM first connects at your destination — so you can buy today and travel in three weeks.
Which networks will you be on in Mexico?
Your phone picks the strongest Mexican network by itself - Telcel, AT&T or Movistar. There is nothing for you to set up.
Average measured mobile internet performance, nPerf barometer (measured 01.01.2025 – 31.12.2025). What you actually get depends on where you are, the time of day and your phone.
The eSIM is not tied to one operator. Once you land in Mexico and switch on data roaming for the eSIM, your phone compares Telcel, AT&T and Movistar, picks the strongest signal and connects there - at Cancún airport just as at AICM in Mexico City. It happens on its own, and you never type in an APN. If you are somewhere with no signal, a quick spell in flight mode or a manual network search usually sorts it out. Worth knowing: Movistar no longer runs its own radio network in Mexico and has been using AT&T's towers since 2020, so in practice there are two physical networks to choose from.
Telcel belongs to América Móvil and reaches furthest inland: Yucatán with Mérida, Valladolid and Chichén Itzá, the coast from Cancún through Playa del Carmen to Tulum and Bacalar, Oaxaca, Chiapas around San Cristóbal de las Casas and Palenque, Baja California Sur with La Paz and Los Cabos. AT&T is strong in Mexico City, Guadalajara, Monterrey, Puebla, Querétaro and Puerto Vallarta, but has noticeable gaps in the Oaxaca and Chiapas highlands, in the interior of Yucatán and in rural parts of Baja. On small islands Telcel is often the only one left standing - Holbox is the best known example. In the sierras, in canyons and in reserves such as Sian Ka'an, expect dead spots regardless of network.
How much data do you need in Mexico?
So you can work it out instead of guessing: how much an hour costs in the apps you actually use on holiday.
The Netflix and Spotify figures come from the providers themselves (Netflix Help Center, Spotify Support, retrieved 28 Aug 2026). The rest are network-operator estimates (o2, Vodafone, EE) and vary with picture quality and reception.
Mexico's registration rule - and why it does not apply to you
Since 9 January 2026 every mobile line issued inside Mexico must be tied to an identity. Mexicans use their CURP; foreigners can present a passport. Unregistered numbers get suspended - the original deadline ran out at the end of June 2026 and was then staggered across the rest of the year for existing prepaid cards according to the last digit of the number. This also covers the Telcel, AT&T or Movistar card you pick up at the airport or at an OXXO: as a tourist you have to register it with your passport, within 30 days of activation.
None of that applies to this eSIM. It is not a Mexican line - it connects to the Mexican networks as a guest, and it has no Mexican number that could be entered anywhere. The regulator CRT stated explicitly that visitors using their foreign line in Mexico do not have to register their phone. For completeness: the same authority points out that a foreign card is not a permanent substitute for a Mexican subscription. Travel eSIMs are built for stays with a fixed validity period, not for living in Mexico for years.

eSIM or a local SIM card in Mexico?
| Compared | Simbye eSIM | Local SIM card |
|---|---|---|
| ID and registration | Nothing to do. The eSIM is not a Mexican line, so there is nothing to register. | Since January 2026 every line issued in Mexico must be tied to an identity, for foreigners with a valid passport. Miss it and the number gets suspended. |
| Time until you are online | Right after landing, before you even reach the baggage belt. | Find the counter, queue, show your passport, fill in a form. |
| Paying | Prepaid before you travel, so nothing unexpected turns up on your phone bill. | Paid in pesos on the spot, and the stands in the arrivals hall at Cancún or Mexico City are usually far dearer than the same card at an OXXO in town. |
| Phone number | No Mexican number, data only. Your usual number stays reachable for calls and texts if you leave it active. | You get a Mexican number, but only with registration and a passport copy at the operator. |
| Second line | Your home SIM stays in the phone and both lines run side by side. | You take your own SIM out and spend three weeks hoping not to lose it. |
| Choice of network | Telcel, AT&T or Movistar, depending on where you are standing. | You commit to one operator at purchase, including for the corners where it is weak. |
| Topping up | Top up online at any time, the same eSIM stays in the phone. | Credit at an OXXO or in the operator's app, menus in Spanish. |
| When something goes wrong | Email support in German or English, wherever in Mexico you are. | Back to the counter, and the advice is usually in Spanish only. |
Why roaming on your home contract gets expensive in Mexico
What your operator charges for Mexico is set out in its international zone price list, and depending on the contract that means either a per-megabyte rate or day and week passes. Neither is often good value for a two or three week trip, and the passes tend to include an allowance that a few days of navigation, photo backups and video calls home will finish off. Worst of all, you cannot see what is piling up while you travel - the bill only reaches you once you are back.
On top of that, Mexico eats more data than people expect. Google Maps runs more or less continuously, because addresses rarely match what the street sign says. Uber and DiDi need to track the ride live. Boarding passes for Volaris and Viva Aerobus, tickets for museums and ruins, a translator, WhatsApp threads with your guide - it adds up. The eSIM turns the logic around: you pay a fixed amount up front, you can see what is left at any time, and you top up when it gets tight. To be straight about what it does not do: it will not make calls on your home number any cheaper, because it carries data and nothing else.
Where the networks actually reach
In the cities and along the tourist corridors Mexico is well covered. Mexico City, Guadalajara, Monterrey, Puebla, Querétaro, Oaxaca City, Mérida and the whole stretch from Cancún through Puerto Morelos and Playa del Carmen down to Tulum are consistently reachable, as are Los Cabos, La Paz, Puerto Vallarta and Mazatlán. In these places you will also see 5G depending on network and handset, while LTE remains the norm across the country.
It thins out as soon as you leave the main road. In the Sierra Norte of Oaxaca, in the Chiapas highlands and in the jungle around Palenque the connection drops out regularly. On Holbox, Telcel is in practice the only one that carries; in the Sian Ka'an biosphere reserve and on the back roads of inland Yucatán between the cenotes there is often nothing at all. You lose the signal halfway across on the ferry to Cozumel or Isla Mujeres, likewise in the Mexico City Metro tunnels, and on long stretches of the Baja highway between Guerrero Negro and San Ignacio expect sizeable dead zones. The practical advice never changes: download Google Maps for the region offline while you are still in town, and WhatsApp yourself the address of your accommodation before you set off.
How does Simbye eSIM work for Mexico?
Get connected in under 2 minutes
Set it up at home
You buy the eSIM and get an email with a link and a QR code straight away. Install it calmly over your own Wi-Fi before you fly. That does not start anything yet: the validity period begins only when you first connect in Mexico.
Land in Mexico
Whether you arrive at Cancún (CUN), Mexico City (MEX or Felipe Ángeles, NLU), Guadalajara (GDL), Monterrey (MTY), Tulum (TQO), Mérida (MID), Los Cabos (SJD) or Puerto Vallarta (PVR): switch on data roaming for the eSIM after landing and select it as your data line. Your phone then connects to Telcel, AT&T or Movistar by itself.
Stay online
Maps, WhatsApp, ride apps and the hotspot for your laptop or tablet work from the first minute. If your data runs low you simply top up - it stays the same eSIM, with nothing to reinstall.
Check Device Compatibility
Make sure your device supports eSIM before purchasing
The apps you actually need in Mexico
In Mexico almost everything runs through WhatsApp: restaurants take bookings there, tour operators send meeting points, guesthouses reply faster than by email. All of that works on this eSIM, because WhatsApp only needs data. What matters is when you set things up: this eSIM carries data only and has no Mexican number, so no SMS code can arrive on it. Set up every app that verifies you by text - WhatsApp, Uber, DiDi, banking apps - at home while your usual number is still reachable. After that they keep running in Mexico on the eSIM's data. The second stumbling block is paying. Mexico is still very much a cash country, and foreign cards are often declined by Mexican apps or left hanging in a verification loop. Pick the "Efectivo" option wherever it exists, draw pesos from an ATM, and download Google Maps for your region offline - in the Metro tunnels, in the sierras and on the ferry to Cozumel you will be glad you did.
DiDi
The most used ride-hailing app in the country and cheaper than Uber in many cities. The fare is fixed before you ride and you see the car, the plate and the driver.
On your very first ride DiDi often asks for prepayment, and foreign cards frequently fail that step. Withdraw pesos beforehand and set "Efectivo" as your payment method, or you will be stuck at the kerb.
Uber
Runs in Mexico City, Guadalajara, Monterrey, Puebla, Mérida and Cancún. Paying the driver in cash has been a normal option in the Mexican app for years.
At Cancún airport a regular UberX is not allowed to collect you at the terminal. The one product that reliably turns up is "Uber Taxi", a licensed airport taxi dispatched through the app at the regulated fare. Quintana Roo has had years of friction between ride-hailing and the taxi unions.
Rappi
Latin America's delivery app: food, supermarket, pharmacy, and in many cities cash brought to your door. It covers every larger town.
Foreign credit cards regularly fail verification here, because the app asks you to confirm the amount again in a different currency. Choose "Efectivo", cash on delivery, and no order gets stranded.
ADO
The big long-distance coach operator in the southeast. Cancún, Playa del Carmen, Tulum, Mérida and Palenque connect more comfortably and cheaply than by rental car, with the ticket as a QR code on your phone.
Whether your foreign card goes through depends on your bank and is a lottery. If the payment breaks off, buy at the terminal counter with cash in pesos - that always works.
Movilidad CDMX
Mexico City's official transit app for Metro, Metrobús, Cablebús and Trolebús, with departure times, connections and service alerts.
You cannot buy tickets in the app. You need the physical "Movilidad Integrada" card, sold at every Metro station and paid for in cash. Coverage in the Metro tunnels is patchy too, so plan the route before you go down.
SkyAlert
Earthquake early warning for your phone, installed millions of times in Mexico. Depending on the distance it tells you seconds in advance how strongly the waves will reach you.
The alert only gets through with a data connection and notifications allowed. One registered region is free, everything beyond that runs on a subscription. It does not replace the official loudspeaker sirens in Mexico City.
