Getting online in Thailand
A travel eSIM is a data plan you install before departure and switch on when you land, so your phone is online in Thailand without roaming charges and without hunting for a SIM counter at arrivals. Your home number stays where it is — the eSIM sits alongside it.
Plans, prices, data amounts and validity are set by our partner and shown on their own page. We do not repeat them here because they change and we do not measure them.
Where you land in Thailand
These are the airports in Thailand with scheduled flights and an IATA code. The minute you step off one of them is the minute an eSIM stops being optional.

Before you buy
Two things worth checking on your own handset, because they decide whether any eSIM works at all: the phone must be eSIM capable, and it must be carrier unlocked. Most phones sold in the last few years are both; phones bought on a carrier contract often are not until the contract ends.
We do not test handsets and cannot tell you whether yours qualifies — your phone's settings screen and your carrier can.
