Why not buy a SIM card at Chiang Mai International Airport?
Airport SIM vendors exist in most arrival terminals, but they come with significant drawbacks.
Overpriced by design
Airport SIM card booths pay premium rent. That cost passes directly to you — often 2–4× the price of the same data sold online.
Queue time when you'd rather move
After a long flight, the last thing you want is to wait in line at a kiosk. An eSIM activates before you reach baggage claim.
Physical SIM card logistics
A SIM card requires ejecting your existing SIM, risking losing it, and going without your home number while abroad.
eSIM is faster and cheaper
LTE.app sends your plan as a QR code. Scan it before you board. By the time you land, your connection is ready.
