Best eSIM for Mexico in 2026: 6 providers compared

How we ranked these eSIMs

Each eSIM is scored on six criteria, weighted for Mexico. Price per GB and network coverage weigh the most: the country is four times the size of France, and as soon as you leave the cities and the tourist areas, only the network used makes the difference. According to the Opensignal report of October 2025, Telcel wins reliability, coverage and download speed, AT&T wins availability. Scores are the editorial team's opinion, not an average of customer reviews.

• Price per GB25 %

  Cost per gigabyte on each provider's cheapest plan, excluding one-off promotions.

• Network coverage25 %

  Getting signal in Mexico City, Cancún, Guadalajara and Oaxaca, on the road to Tulum, in Chiapas and in Baja California.

• Reliability15 %

  Connection stability, seriousness of the partner carrier and the provider's reputation.

• Support15 %

  Available channels, opening hours, human or automated answers.

• Activation and app10 %

  How simple the install is, how clear the app is, data usage tracking.

• Plan flexibility10 %

  Choice of volumes and durations, unlimited, top-ups, tethering.

On these criteria, voilà eSIM comes out on top thanks to its two networks, Telcel and AT&T, its clear app and its 24/7 human support, despite a price per GB in the upper half of the comparison (€2.09/GB). Airalo takes second place with the lowest price per GB and the cheapest unlimited, Esimzon third with AT&T named on every plan and the cheapest small plans.

Scores are the opinion of the eSIMrat editorial team, based on the criteria above, not customer reviews. eSIMrat earns a commission on links to its partners, which does not affect the ranking.

Each Mexico eSIM in detail

1. 

   1. voilà eSIM

   7.6/10
   €2.09/GBTelcel and AT&TData plans, 1 to 50 GB

   ✓Two networks, 5G, 24/7 human support

   voilà eSIM is the only eSIM in the comparison to combine Telcel and AT&T, the only two carriers that own a nationwide network in Mexico. Telcel, with more than half of the market, is the network that reaches furthest into the countryside and along the roads, AT&T takes over in the big cities. 5G is advertised depending on the network, 4G everywhere else.

   The rate drops to €2.09/GB on the 50 GB plan, in the upper half of the comparison: Airalo, Yesim, Saily and Esimzon do better per GB, only Ubigi does worse. Plans run from 1 to 50 GB over 7, 15 or 30 days, with no commitment, and tethering is included. The code ESIMRAT gives 5% off, see the promo codes page.

   It is the easiest offer to get started with: the eSIM installs in two minutes from an app that is easy to use, and human support answers 24/7, which matters with a seven hour time difference between Mexico City and Europe. That value for money, two networks included, earns it first place, even though four providers do better on price per GB alone.

   Pros

   • ✓Telcel and AT&T on the same eSIM, 5G advertised
   • ✓eSIM simple to install, easy-to-use app
   • ✓Human support, 24/7, tethering included

   Cons

   • ✗Price per GB in the upper half of the comparison
   • ✗No unlimited plan

   2. Airalo

   7.4/10
   €0.82/GBMovistarData plans, data with calls and texts, unlimited, regional

   ✓The lowest price per GB, cheapest 30-day unlimited

   Airalo, the market pioneer, crushes the comparison on price: €0.82/GB on the 50 GB plan, more than twice as cheap per GB as the runner-up, and its 10 GB 30-day plan is also the cheapest of the six. Its 30-day unlimited is the cheapest in the comparison, and it is the only provider here to sell plans with Mexican calls and texts, handy to book a restaurant or call a driver.

   The advertised network is Movistar, which no longer has its own network in Mexico and relies on AT&T's and on the Altán wholesale network: good coverage of the cities and tourist areas, less solid than Telcel in the countryside. The app is the most complete of the six, with top-ups and usage tracking, and a North America plan covers Mexico, the United States and Canada. Support, in English, can be slow.

   Pros

   • ✓The lowest price per GB in the comparison, by far
   • ✓Cheapest 30-day unlimited, plans with calls and texts
   • ✓Complete app, North America plan

   Cons

   • ✗Movistar, with no network of its own, less solid than Telcel outside the cities
   • ✗Support in English, sometimes slow

   3. Esimzon

   7.0/10
   €2.11/GBAT&T MexicoData plans 1 to 15 GB, 30 days

   ✓AT&T named on every plan, cheapest small plans

   Esimzon is a prepaid reseller that names its carrier on every plan: in Mexico, it is AT&T, the second nationwide network, on 4G. Its lowest rate per GB comes to €2.11/GB on the 10 GB plan, in the middle of the comparison, and its 1 and 3 GB 30-day plans are the cheapest of the six at those volumes.

   The limits are elsewhere. The catalogue stops at 15 GB, with no unlimited and no 5G, every plan lasts 30 days, prices are shown in dollars on its site (the euro follows the daily rate), support is by email or chat, in English, and activation goes through a QR code, without an app as polished as the leaders'.

   Pros

   • ✓AT&T named on every plan, 4G
   • ✓The cheapest 1 and 3 GB plans in the comparison

   Cons

   • ✗No plan above 15 GB, no unlimited, no 5G
   • ✗Prices in dollars, support in English, no proper usage-tracking app

   4. Yesim

   6.9/10
   €1.80/GBLocal networksDaily, data and unlimited plans

   ✓Second-lowest price per GB, reusable eSIM

   Yesim, a Swiss provider, offers the widest range: daily plans, classic data plans up to 20 GB and an unlimited offer from 1 to 30 days. The best price per GB drops to €1.80/GB on the 20 GB plan, second in the comparison behind Airalo.

   The eSIM can be reused from one trip to the next, which saves a new install every time you leave. On the other hand, Yesim does not name the Mexican carrier it uses before purchase, its unlimited is the most expensive of the three in the comparison, and support is limited to chat.

   Pros

   • ✓Second-lowest price per GB in the comparison
   • ✓Reusable eSIM, daily plans and unlimited available

   Cons

   • ✗Mexican carrier not named before purchase
   • ✗Most expensive unlimited in the comparison, support by chat

   5. Saily

   6.5/10
   €2.05/GBLocal networksData plans, 1 to 20 GB, and unlimited

   ✓By Nord Security, built-in security

   Saily is the eSIM from Nord Security, the maker of NordVPN. The app is simple, with an ad and tracker blocker and built-in web protection, and chat answers 24/7 in English. An asset on hotel and café public Wi-Fi.

   In Mexico, the best price per GB comes to €2.05/GB on the 20 GB plan, in the middle of the comparison, and its 30-day unlimited is the second cheapest. Saily does not name the carrier it uses before purchase.

   Pros

   • ✓Built-in ad and tracker blocker
   • ✓24/7 chat, second-cheapest 30-day unlimited

   Cons

   • ✗Price per GB in the middle, nothing more
   • ✗Carrier not named before purchase

   6. Ubigi

   6.2/10
   €2.40/GBLocal networksData plans, 1 to 10 GB, and 7-day unlimited

   ✓Prices in euros, NTT group

   Ubigi belongs to Transatel, a subsidiary of the NTT group, a mark of seriousness, and shows its prices in euros with top-ups in the app. But in Mexico, its catalogue is the shortest in the comparison: 1, 3 and 10 GB, and a 7-day unlimited only.

   Its best price per GB comes to €2.40/GB on the 10 GB 7-day plan, the highest of the six, with no carrier named before purchase. Support is by ticket, in English and French. For a short stay where price matters little.

   Pros

   • ✓Prices in euros, top-up in the app
   • ✓Support by ticket in French

   Cons

   • ✗The highest price per GB in the comparison
   • ✗Catalogue capped at 10 GB, unlimited over 7 days only
