Thailand eSIM works by digitally adding a mobile plan to your device. Simply purchase a prepaid Thailand eSIM, install it through the Klook app or a QR code, and get connected as soon as you arrive. Hotspot and tethering are supported and you can easily add additional data linked to your main eSIM if you run out of data.
