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 DMK, on the local networks, with nothing to log in to. The plan only starts counting when it first connects in Thailand, so you can buy it weeks ahead.
Installs in about a minute. No app, no account. Works on your phone or a full refund.
