Internet at CancĆŗn International Airport (CUN) matters for transfer details, hotel messages and navigation after arrival. Airport Wi-Fi can help, but a prepared eSIM avoids depending on one terminal network.
Save the terminal, accommodation address and transfer confirmation before travel because pickup arrangements can vary.
NoveSIM travel eSIMs are data-only and do not include a Mexican number, conventional calls or SMS.
Quick answer: Install a Mexico-covering eSIM before departure, enable it after landing and test with airport Wi-Fi off. Keep transfer details offline and prevent the home SIM from using roaming data.
