Have data before the Wi-Fi question comes up
Airport Wi-Fi is fine for a message home and useless for the things you need on arrival: booking a ride, finding the hotel, checking in with the driver. An eSIM installed before you fly connects the moment your phone leaves airplane mode at CUN, on the local networks, with nothing to log in to. The plan only starts counting when it first connects in Mexico, so you can buy it weeks ahead.
Installs in about a minute. No app, no account. Works on your phone or a full refund.
SIM cards at CUN
Telcel, Movistar and AT&T stands in Terminal 3 near baggage claim and the exits, about 7am-11pm. Airport tourist SIMs run roughly 200-500 MXN; the same SIM is cheaper at an OXXO in town.
Arriving at CUN
After customs you walk a corridor of timeshare and tour reps wearing official-looking lanyards; keep walking. Uber and DiDi don't pick up at the terminals, so use a pre-booked transfer or an authorized taxi outside.
