Bought the wrong plan? An unused, never-activated eSIM can be refunded in full within 30 days of purchase. See our refund policy for the full terms.
Fixed data plans give you a set amount of data, for example 1 GB or 5 GB, to use at full speed for the whole plan period. When it runs out, you top up or buy again. Pick this if you know roughly how much you'll use.
Unlimited plans have no total data cap for the plan period, but each day includes a high-speed allowance. Once you use that day's allowance, you carry on at a reduced speed. Reduced-speed data has a daily limit too, and if you reach it, data pauses until the allowance resets 24 hours after you activate the eSIM. Pick this for heavier or less predictable use. A fair-use policy applies.
Pay As You Go is not a plan at all. You add credit once and it comes off by the megabyte at the local rate as you use it, so you never pay for data you do not finish. Credit never expires, data pauses when the balance hits zero, and the same eSIM keeps working across every country we cover. It costs more per gigabyte than a plan, so pick this for light or hard to predict use rather than heavy days.
Add your other stops and we check whether one regional eSIM costs less.

Telcel is the biggest network and bills itself as the widest-reaching, with AT&T the other main one. Telcel's coverage maps mark guaranteed and non-guaranteed areas separately, which is worth a look before a rural drive.
Canada's travel advice says the telecom network is not reliable in rural areas. On major toll highways, the Ángeles Verdes patrol offers free roadside help on 078.
Mexican mobile lines must be registered to a named holder, and foreigners register with a passport under the regulator's line-registration rules. Bring yours if you plan to buy a local SIM.
It works anywhere in the country.
Funcionó en Cancún y Tulum. En los pueblos pequeños la velocidad bajó un poco.

Pick a row, watch the phone.
Everything you need to know before you buy.
Your Mexico eSIM connects automatically to Telcel, AT&T, and Movistar, switching to the strongest available signal. Telcel has the widest reach outside the big cities and resorts.
