Best eSIM for Mexico: how to choose, and what to buy
Short answer: For Mexico, 5 GB at £14.99 is the comfortable default for one to two weeks. Coverage is strong in cities and resorts and drops off quickly once you leave them.
Mexico splits cleanly in two for connectivity: the places most visitors go, which are well covered, and the places you drive to between them, which often are not.
Which plan to buy for your trip length
For Mexico we currently sell 5 plans, from 1 GB for £3.49 up to 20 GB for £32.49. Matching those to the length of a trip gives the table below.
| Trip length | Light use (maps, messaging) | Moderate use (plus social, photos) |
|---|---|---|
| 3 days | 1 GB · £3.49 (7 days) | 3 GB · £9.49 (30 days) |
| 7 days | 3 GB · £9.49 (30 days) | 5 GB · £14.99 (30 days) |
| 14 days | 3 GB · £9.49 (30 days) | 10 GB · £19.99 (30 days) |
| 30 days | 10 GB · £19.99 (30 days) | 20 GB · £32.49 (30 days) |
Planning figures, not guarantees: roughly 200 MB a day for light use and 500 MB a day for moderate use. Daily video streaming, video calls and large downloads use far more. The plan shown is the cheapest one in our live catalogue that is both big enough and valid long enough.

Resorts and cities versus the road between them
Mexico City, Guadalajara, Cancún, Tulum and the main resort strips have dependable coverage. Rural stretches, cenote country and long highways between towns are where it fails, so download offline maps before any drive that takes you out of a town, and tell someone your route.
Who it is for
Travel to Mexico is often a short, high-use trip: rideshare, maps, messaging, a lot of photos shared back home. A 3 GB plan is workable for a week of that if you use hotel Wi-Fi to upload photos in the evening.
Coming from the US or Canada
If you normally use a North American SIM, check your carrier’s Mexico roaming before assuming it is free, because inclusions vary by plan. If it is not included, a local eSIM is usually cheaper than the day-pass rate.
