Useful travel information
A few details that help before and during your trip.
Mobile coverage in Thailand
Thailand's mobile network is served by three main operators: AIS, DTAC (now merged with True), and True Move H. 4G LTE coverage is strong across Bangkok, Chiang Mai, Phuket, Pattaya, and all major cities, with reliable connectivity along main highway and rail corridors. Popular islands including Koh Samui, Koh Phangan, Koh Tao, and Koh Lanta have coverage in their main resort and town areas, with signal weakening on remote beaches and jungle interiors. Northern highland areas near Myanmar and Laos, jungle national parks including Doi Inthanon and Khao Yai, and some remote island areas may have more limited signal. MobiSIM connects through supported Thai networks to deliver reliable data across Thailand's main cities and tourist destinations.
