eSIM for Mexico: connected from beach to city
An eSIM for Mexico keeps you connected from the Riviera Maya to the Mayan temples and the energy of Mexico City. This guide explains everything with tables, tips and a FAQ.
Do I need an eSIM in Mexico?
Yes, usually. Mexico is not an EU country, so your home data is charged at the expensive outside-Europe rate. An eSIM gives you a generous, fixed amount of data at a price known in advance, while your home number stays active for calls and codes.
Outside the EU: on arrival, turn off the mobile data of your home SIM card and use only the eSIM, to avoid expensive roaming.
