Thailand: Tourist SIMs, Grab, LINE & Mobile Pay (2026)

Updated 2026-04-11

Tourist SIM + Grab/LINE covers most city trips

Getting online

Airport and mall counters sell tourist data bundles; eSIM is available for compatible phones. Compare with your home roaming package if the trip is very short.

Grab & LINE

Grab handles rides and food; payment options depend on account region. LINE is common for promos and merchant chat—SMS verification needs a working number.

Safety & money

Keep some cash for stalls and islands.
Turn on card transaction alerts.
Verify ride-hailing plate numbers before boarding.

Prep list: before you fly.
