Airport WiFi at BKK
Registration required to connect — look for the sign-in page after joining the network.
Thailand eSIMs from AIS, dtac/True, Airalo, or Holafly are cheap and easy to activate on arrival; True and AIS counters in the Suvarnabhumi arrivals hall also sell physical SIMs for those who prefer it.
The free wifi caps out at 3 hours and needs the 'Sawasdee by AOT' app plus an email sign-up to activate — install the app before you land so you're not doing it on slow airport data.
