With a travel eSIM installed before you fly, you are online the instant you land at Bangkok (BKK or DMK) or Phuket (HKT), ready to book a Grab and open maps. It is data-only on one of Thailand's main 5G networks (AIS, TrueMove H or dtac) where available.
Online before the taxi queue
The eSIM activates when it first connects at the airport, so you can book your Grab, message your hotel and check your route before you reach arrivals. No SIM kiosk queue, no slow airport WiFi sign-in.
The quick setup on arrival
- Turn on the eSIM line.
- Enable data roaming for it.
- Set it as your data line.
You connect automatically, and your home SIM stays in for your own number.
How much data
A short trip fits in 5 to 10GB; two weeks of islands and uploads is more like 15 to 25GB. See how much data for two weeks in Thailand.
