Mexico has a few national networks and has been rolling out a requirement to link mobile lines to a person's identity in 2026. Whether that touches visitors using a foreign travel eSIM is not confirmed, so check before a long stay.
Mobile networks in Mexico
The main networks are listed below. A travel eSIM connects to one of them or to a partner, and the provider decides which, so the network named in the plan details is worth a look if coverage matters on your route.
SIM rules and ID for visitors
Mexico introduced registration of mobile lines against identity in 2026, covering prepaid, postpaid and eSIM lines, and foreigners can register with a passport. We could not confirm how it applies to visitors using a foreign travel eSIM, so verify the current rule with the operator or regulator.
Rules change
Registration and phone rules are updated by governments and operators without much notice. Check the current position with the operator or the provider before you travel.
Using a travel eSIM in Mexico
Line registration
The registration applies to lines on the Mexican market. Lines that are not registered can be suspended, though emergency numbers keep working.
Foreign travel eSIMs
Sources read here do not say whether a foreign travel eSIM is affected. Check with your provider if you plan to stay long.
Network choice
Coverage in remote areas varies between networks, so check the network behind the plan for beach or mountain routes.
Data only
Most travel eSIMs have no Mexican number, so keep your home SIM for texts.
Check before you fly
