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