Telcel, Movistar and AT&T Mexico cover cities and federal highways on 4G and 5G; Copper Canyon remote tracks, Sian Ka'an lagoon routes and some Pacific surf villages fade. CDMX metro has partial underground coverage. Check the network list above for Mexico before you fly; it shows what is available right now, including options such as Movistar, Altan, AT&T, Telcel.
Prepaid SIMs are sold at OXXO, airports and operator stores with passport registration. Tourist eSIMs are common; a local number still helps with Rappi and WhatsApp concierges. That still makes sense if you will live in Mexico City for months and need local calls. For a holiday or short work trip, most people only need data — and NXTL gives you that without the desk stop: install at home, keep your usual number for calls and bank texts, pay only for the gigabytes you use.
There is no complicated Mexico-only product to learn. NXTL is one global eSIM: the same profile you might use elsewhere works here on Movistar, Altan, AT&T, Telcel when listed. Land, turn data on, and go — rates for Mexico are shown live on this page because they can change.
If Mexico is one stop on a longer route, NXTL is built for that. Use data around Mexico City and Cancún, then keep the same balance wherever NXTL has coverage next. You are not locked into a single-country tourist pack.
ADO overnight buses between CDMX and Oaxaca text platform changes in Spanish when you have a Mexican number or roaming data. NXTL is built for that kind of Mexico trip: data when you need it, without buying a new pack for every change of plan.
