Find the perfect plan for Thailand
Staying connected in Thailand
What the coverage maps do not tell you, and what you will actually use the data for.
Where the signal actually drops
AIS, TrueMove and dtac cover Bangkok, the tourist islands and the main routes well. Gaps appear in the northern hills around Pai and Mae Hong Son, in national parks, and on the smaller southern islands away from the main beach strips. Boat crossings lose signal.
What you will use your phone for here
Grab for taxis and food delivery is near-universal, QR payment through Thai banking apps is widespread but mostly for residents, and Google Translate gets constant use since Thai script is impenetrable to most visitors.
Before you go
Island transfers and long-tail boats are the connectivity gap that catches people out, particularly when confirming an onward booking.
How much data you will actually need
Moderate to high. Grab, maps, translation and photo uploads add up faster than in Europe.
