Mexico is one of those countries that never stops surprising me. From colorful colonial towns and ancient Maya ruins to Caribbean beaches, Pacific coast sunsets, jungle waterfalls, volcanoes, deserts and one of the most exciting capital cities in the world, the list of best places to visit in Mexico in endless.

I first wrote this Mexico travel guide years ago, but after spending more than 8 months traveling around the country, driving thousands of kilometers in rental cars, taking almost 15 domestic flights and visiting 26 of the 31 Mexican states as of 2026, it was time for a serious update.

Are you traveling to Mexico and looking for the best eSIM for Mexico in 2026? Then my first advice is simple: do not just compare prices, data plans or discount codes. In Mexico, the most important thing is the mobile network behind your eSIM.

After traveling through 23 out of 32 Mexican states during a 6-month road trip, I learned that Mexico is not just Cancun, Tulum, Playa del Carmen and Mexico City. Once you travel beyond the main tourist hotspots, mobile network coverage becomes very important.

That is why Traveltomtom only recommends Mexico eSIMs that clearly operate on the Telcel network. Based on the latest prices, plans and network information, Airalo is my top recommendation for Mexico because it uses Telcel and offers the best overall value for most travelers.
