Best eSIM for Mexico in 2026: My 5 Picks Compared

Your plane has landed in Cancun, and the immigration line barely moves. Halfway through it, the driver you booked sends a WhatsApp photo of his sign, your name in thick black marker. He wants to know which door you'll use. You want to answer him from the line, not from the curb.

Online, Mexico eSIMs look almost the same. Off the main routes, what really differs is the Mexican network behind each plan, and most sale pages hide it in the plan details. Some plans even list two networks and still put you on one set of towers. That network decides whether your phone still finds a signal on a long drive between towns.

On one day I read the plan pages of seven travel eSIMs that sell Mexico, wrote down the network each plan uses and lined up their prices for the same sizes and the same number of days. Five of them made the cut, each with the Mexican network it really uses.

Key things to consider when using an eSIM in Mexico

• How much data, for how many days: A week on the Caribbean coast is light use: directions, chats and beach photos. A month of remote work in Mexico City is not. If your partner's phone runs off your hotspot, count it twice. Most 5 GB to 20 GB plans for Mexico last 30 days, longer than most holidays.
• Signal from the capital to the coast and beyond: Mexico City and the Riviera Maya are well covered. Plan on 4G. 5G still reaches less than half of Mexicans. The signal thins between towns.
• What your money buys: The plans that cost least run on AT&T's network. A plan with Telcel or Altán costs a few dollars more, and it can still find a signal where AT&T's loses it.
• Calls, texts and a number: Messages and calls in apps run over data, so a number rarely matters on a holiday here. A few plans add minutes and a number for the trips where you do need one.

My picks

• Best value with Telcel: eSIMo eSIM for Mexico, 10 GB for 30 days at $19.90, with Telcel as well as AT&T's network.
• Best for city and beach trips: Nomad eSIM for Mexico, 10 GB for 30 days at $15.50, less than my other picks ask.
• Best unlimited data: Airalo eSIM for Mexico, unlimited for 7 days at $23.50, with 3 GB of fast data a day against Nomad's 2 GB, and plans up to a whole month.
• Best for long drives off the main routes: Ubigi eSIM for Mexico, 10 GB for 30 days at $24.00, on Telcel, Movistar and Altán.
• Best for Mexico and the USA: Roamless North America eSIM, 10 GB for 30 days at $19.95, with the USA and Canada on the same plan.

Best eSIM for Mexico: 10 GB and 20 GB plans compared

Of the seven eSIMs I compared, Nomad costs least for both sizes, so it is my pick on price. Roamless comes next on 10 GB but runs on Movistar alone with no 5G, while eSIMo, Ubigi and Jetpac cost more and add Telcel.

You can compare every Mexico eSIM plan by size and price on our Mexico page.

Unlimited data in Mexico: Airalo, or Jetpac for a month

Airalo is the best eSIM for Mexico with unlimited data. Each day on Airalo starts with 3 GB at full speed, then 1 Mbps, on plans from 3 days to a full month. Nomad's unlimited week costs $1.50 less but keeps only 2 GB a day at full speed. I recommend unlimited only when you call home on video every day or run the laptop on your phone.

On a week in Mexico City with a video call home every evening and lots of photos to send, Airalo gives you 21 GB at full speed. If the photos eat the day's 3 GB, the call slows to 1 Mbps until the next day's 3 GB.

For a full month, my pick is Jetpac instead, because its 30-day unlimited on Telcel costs $56.50, $5.50 less than Airalo's month. Unlike most Jetpac plans for Mexico on October 13, 2026, this one isn't on sale. Jetpac lists no 5G on Telcel.

Best eSIM for Mexico travel: my five picks reviewed

eSIMo eSIM for Mexico: best value with Telcel

Pros

• Telcel plus a second Mexican network
• 20 GB plan with Telcel
• Hotspot sharing on its plans
• Renew or extend anytime in the app

Cons

• 10 GB costs more than Nomad's

Take eSIMo's 10 GB for 30 days at $19.90 if your trip leaves the main routes, because eSIMo names Telcel on its Mexico plan, next to AT&T and Movistar.

Proof: eSIMo confirms its Mexico eSIM connects to AT&T, Movistar and Telcel

Your laptop can share the phone's data: eSIMo says its plans support personal hotspot sharing.

Proof: eSIMo confirms its plans support personal hotspot sharing for a laptop or tablet

On speed, the Mexico page promises "fast LTE/5G".

Proof: eSIMo confirms fast LTE/5G on its Mexico eSIM page

The plans on eSIMo's site for Mexico run from 1 GB to 20 GB. Every plan lasts 30 days, except the 1 GB plan, which has 7, counted from when you activate the eSIM on arrival. For a heavier month, 20 GB costs $29.90. You can renew or extend from your eSIMo account or app. The app makes outgoing calls. Incoming calls don't come through it.

eSIMo plans for Mexico

• 1 GB for 7 days: $3.90
• 3 GB for 30 days: $9.90
• 5 GB for 30 days: $12.90

Nomad eSIM for Mexico: best for city and beach trips

Pros

• Lowest 10 GB, 20 GB and unlimited-week prices of my picks
• Hotspot on every Mexico plan
• 5G on 20 GB and unlimited plans

Cons

• 10 GB plan: 4G only

For 10 GB, 20 GB and a week of unlimited data, Nomad costs less than my other four picks. That price makes it my main pick. On Trustpilot, Nomad is rated 4.3 out of 5 from 47,141 reviews.

Nomad's Mexico plans all run on AT&T's network. The 10 GB plan is 4G only, and 5G comes with the 20 GB and unlimited plans. Skip Nomad for trips far from the cities, where a plan with Telcel or Altán gives your phone a second network to try.

Your Nomad plan starts when you connect in Mexico. Nomad's Mexico page gives 60 days to activate. The 1 GB to 10 GB plans start by themselves 30 days after you buy, so buy those within a month of the flight. You can add data to a fixed plan, not to an unlimited one.

On Nomad's unlimited plans, you get 2 GB a day at full speed, then 1 Mbps, and hotspot is allowed.

Proof: Nomad confirms its unlimited Mexico eSIM gives 2 GB a day at 4G/5G, then 1 Mbps, on AT&T / Movistar with hotspot

The full-speed data comes back every 24 hours from activation.

Airalo eSIM for Mexico: best unlimited data

Pros

• Unlimited for a whole month
• No hotspot or device limit on unlimited plans
• Plans with minutes, texts and a number
• 50 GB for 30 days at $45.00

Cons

• Unlimited plans slow to 1 Mbps after 3 GB a day
• 30-day unlimited costs more than at most other providers
• Number plans need an ID check

I pick Airalo for unlimited data because its unlimited plans keep the first 3 GB of each day at full speed, then slow to 1 Mbps.

Proof: Airalo confirms its unlimited Mexico eSIM slows to 1 Mbps after 3 GB a day

Two weeks between Mexico City and the coast fit the 15-day plan at $43.00. Staying three more days? Top up the same eSIM instead of buying a new one. Skip Airalo for a light week in one city, where a fixed 10 GB plan does the job for less.

Airalo's eSIM can switch between Movistar and AT&T: "This eSIM may switch between the following networks, based on availability and speed." Its 5G comes on AT&T's network.

Proof: Airalo confirms its Mexico eSIM can switch between Movistar (4G) and AT&T (5G)

On unlimited plans Airalo puts no limit on hotspot or on how many devices you connect, so a second phone can share the data.

Proof: Airalo confirms there is no limit on hotspot or on the number of devices you connect on its unlimited plans

An unlimited plan starts when the eSIM connects to a network in Mexico. You have 365 days from purchase to start it, so you can buy it long before the trip.

Proof: Airalo confirms its unlimited Mexico eSIM starts when it connects to a network there, and you have 365 days from purchase to start it

For calls, Airalo sells "Data / Calls / Texts" plans, and you verify your identity before you buy one. 10 GB with 100 minutes and 100 texts for 30 days costs $26.00, and this plan gives you 90 days from purchase to start it, not 365. In Airalo's words: "Only local calls are supported. A phone number will be assigned upon the eSIM's activation at the destination."

Proof: Airalo confirms its 10 GB calls plan for Mexico assigns a phone number for local calls on activation

Airalo plans for Mexico

• 1 GB for 3 days: $4.00
• 5 GB for 30 days: $13.00
• 10 GB for 30 days: $18.50
• 20 GB for 30 days: $31.00
• 50 GB for 30 days: $45.00
• Unlimited for 3 days: $10.50
• Unlimited for 7 days: $23.50
• Unlimited for 15 days: $43.00

Ubigi eSIM for Mexico: best for long drives off the main routes

Pros

• Altán, Telcel and Movistar on one plan
• 5G on Movistar
• 2 Mbps after the daily data on unlimited plans

Cons

• 10 GB costs more than at most other providers

Pick Ubigi eSIM for Mexico when you drive far from the big cities. Ubigi is the only pick on Altán, the network with the widest guaranteed 4G in the figures of Mexico's telecoms regulator. eSIMo costs $4.10 less but has no Altán, and in the cities Nomad is cheaper still.

Ubigi's Mexico plan page names Altán, Movistar and Telcel, and it ticks 5G for Movistar.

Proof: Ubigi confirms its Mexico eSIM runs on Altán, Movistar and Telcel, with 5G on Movistar

The plan to buy is 10 GB for 30 days at $24.00. For two heavy weeks, take the 15-day unlimited at $58.00. Ubigi's fair use policy gives 5 GB a day at full speed on unlimited plans like this one, then 2 Mbps, and resets every 24 hours.

Proof: Ubigi confirms 5 GB a day at full speed on this Mexico unlimited plan, then 2 Mbps, reset every 24 hours

Hotspot works too. Ubigi's plan page says "Data sharing allowed."

Proof: Ubigi confirms data sharing is allowed on its Mexico eSIM

Your plan starts when you arrive in Mexico, and Ubigi's Mexico pages mention no calls, texts or number. Save an offline map before you leave the main roads anyway.

Ubigi plans for Mexico

• 500 MB for 2 days: $3.00
• 1 GB for 30 days: $5.00
• 3 GB for 30 days: $9.00
• 10 GB for 7 days: $22.00
• 10 GB for 30 days: $24.00

• Unlimited for 15 days: $58.00

Roamless eSIM for Mexico: best for Mexico and the USA

Pros

• North America plan covers 5 places
• One balance for Mexico, the USA and Canada
• Hotspot: "Unlimited"

Cons

• No 5G listed in Mexico

Roamless is my pick when the trip crosses into the USA: one eSIM and one balance cover Mexico, the USA and Canada. $19.95 buys 10 GB for 30 days on the North America plan, which adds Puerto Rico and the US Virgin Islands. For a trip in Mexico alone, a Mexico-only plan costs less.

At checkout, use our code CopiedESIMSPOTTER.

Pay as you go keeps one balance across the three countries too, and in Mexico alone 1 GB costs $2.95 and never expires. For more data, 20 GB on the North America plan costs $39.95.

In Mexico, Roamless connects to Movistar on 4G, with no 5G listed, and hotspot is "Unlimited".

Proof: Roamless confirms its Mexico eSIM runs on Movistar 3G/LTE/4G with unlimited hotspot

The Mexico unlimited plans give 3 GB a day at full speed, then 1 Mbps, and they are "Valid only in Mexico".

Proof: Roamless confirms its unlimited Mexico eSIM gives 3 GB a day at full speed, then 1 Mbps, reset every 24 hours

Fixed data plans and pay as you go have "No speed limit", and a plan starts with your first data use. Calls go through the app from $0.01 a minute. Roamless Numbers come from the US, Canada, the UK and Australia for $6.95 a month, not from Mexico.

Roamless plans for Mexico

• Pay as you go, 1 GB: $2.95
• 5 GB for 30 days: $12.95
• 10 GB for 30 days: $18.45
• 20 GB for 30 days: $30.95
• 50 GB for 30 days: $67.45

Mexico eSIM coverage: the network behind each plan

Coverage in Mexico follows the Mexican network your eSIM connects to, not the eSIM brand in your app.

CRT's coverage report, from Mexico's telecoms regulator, names four mobile networks: Telcel, AT&T, Telefónica Movistar and Altán, a wholesale network that sells its signal to other brands. On CRT's guaranteed maps, Altán reaches the most people with 4G, 88.1%. Counting all its maps, Telcel leads with 94.4%.

Two of those four share one radio network. Telefónica Movistar México says its customers have used AT&T México's 3G and 4G networks since 2020, and its 5G since 2022. So when a plan names AT&T and Movistar, I count it as one network, because Movistar's traffic runs on AT&T's. The deal now runs to 2030.

The network on each of the seven eSIMs:

• Airalo: Movistar and AT&T, no Telcel
• Nomad: AT&T and Movistar
• Roamless: Movistar
• AirHub: AT&T on its 1 GB to 20 GB plans
• eSIMo: AT&T, Movistar and Telcel
• Ubigi: Altán, Movistar and Telcel
• Jetpac: Telcel only

Only Ubigi names Altán.

Telcel's guaranteed 4G reaches the fewest people in the far south:

eSIM or a local SIM card in Mexico?

For any trip to Mexico, the best SIM card is an eSIM. Buy it online before the flight and set it up at home: how to install an eSIM on iPhone and how to install an eSIM on Android. You land with the internet already working.

A prepaid SIM card from a phone shop in Mexico makes sense only when you need a Mexican number for local calls. Some eSIMs sell a number as well: Airalo's calls plan assigns one for local calls, and AirHub's plans with calls come with a US number. Before you choose, read my guide to eSIM vs SIM card for travel.

Visiting the USA too? One eSIM for Mexico and the USA

For Mexico and the USA on one eSIM, my pick is Roamless North America, because one plan and one balance cover both countries and Canada. The North America plans of the others cost more for the same 10 GB:

Ubigi's Americas plan doesn't work for Canadian residents back in Canada.

Change planes in the USA, and the same eSIM works there and in Cancun. To see every plan that covers Mexico, the USA and Canada, compare every North America eSIM plan on eSIM Spotter. If most of the trip is in the USA, see my guide to the best eSIM for the USA.

If the route goes south to Guatemala or Belize, pick every country of your route on eSIM Spotter and see which plans cover all of them. AirHub's North America 20 GB for 30 days at $30.89 also covers Guatemala, El Salvador and Nicaragua, but not Belize.

My verdict: which eSIM is best for Mexico?

For Mexico City, Cancun and the beach towns, the best eSIM for Mexico travel is Nomad, for its price on 10 GB and 20 GB. Off the main routes, the best eSIM card for Mexico has more than one real network. The south is where even Telcel's 4G is weakest, so take a plan with Telcel and a second network: eSIMo adds AT&T, Ubigi adds Altán and Movistar.

For unlimited data, take Airalo, with plans from 3 days to a whole month. Jetpac wins a whole month on Telcel if you can live without 5G. Crossing into the USA? Take Roamless.
