AIS or True at CNX arrivals — tourist SIM 7–30 days (300–450 baht), passport copy, staff installs. Airport slight markup vs 7-Eleven but worth immediate Grab. eSIM (Airalo/Holafly) fine if phone supports — activate before immigration. DTAC third option, similar coverage. Need data for maps and Grab day one; wifi everywhere but patchy on Doi Suthep.

Airport AIS counter 5 min — tourist 30-day ~450 baht, staff sets up APN.

True 15-day sometimes promo 199 baht at mall — not worth detour day one.
