Mexico's mobile networks — Telcel, AT&T Mexico, and Movistar — cover the resort belt (Cancún, Playa del Carmen, Tulum, Cabo, Puerto Vallarta) plus Mexico City, Guadalajara, and most highways with solid 4G/LTE. A Mexico eSIM activates instantly at the airport so you can order an Uber, use Google Maps in Roma Norte, or check surf reports in Sayulita without paying your home carrier's $10–$15/day roaming rate. Many regional plans cover Mexico, the US, and Canada on a single eSIM — useful if you're road-tripping across the border.
Best time to visit: November–April (dry season)
