eSIM data plans for Mexico

Plans for Mexico split into two types: gigabyte allowances on Altan's network, and day-based unlimited plans on AT&T. Picking between them mostly comes down to how much data a trip needs and how long it lasts.

Fixed data plans on Altan

These fixed data plans run from 1GB over seven days up to 50GB over thirty days, so a short city trip and a month-long stay can both be matched to a size rather than paying for data that goes unused. When a plan's data runs out, it stops, and a top-up on the same eSIM brings it back, so the size chosen at the start does not have to be the last word on a trip that runs longer or uses more than planned.

Unlimited plans on AT&T

These unlimited plans are sold by the day, from a single day up to thirty, and suit a traveller who would rather not track a gigabyte count at all. They carry a fair use policy: past a daily amount, speed is reduced for the rest of that day, so a heavy single day of use is still covered without picking a separate size.

Hotspot and timing

Hotspot and tethering are available on every plan here, fixed data and unlimited alike, so a laptop or a second device can share the connection. Validity begins at the first connection to a network in Mexico, not at purchase, so the eSIM can be installed before departure without losing any of the plan's days.
