Summary

Same networks, different pricing

In Mexico, Telcelhas the widest 4G/5G footprint, with AT&T Mexico and Movistar also available. YonoSIM, Airalo, and Holafly are all travel eSIMs that ride these local networks — so raw coverage in Cancún (CUN) and Mexico City (MEX) is comparable across providers. What actually varies is the data model, validity, and top-ups: YonoSIM and Airalo price by the gigabyte, whereas Holafly is known for its unlimited-data plans that trade a higher price for no data cap.

Sizing your Mexico data

For a week split between Cancún beaches and Mexico City museums, a 5GB / 30-dayplan covers maps, rideshare, restaurant lookups, and social uploads with room to spare. Heavy streamers should step up to 10GB or consider Holafly's unlimited option; light travelers on a short trip can drop to 3GB. Because YonoSIM and Airalo tiers are prepaid and flat, you always know the cost up front — and YonoSIM top-ups let you add data mid-trip without re-installing a profile.
