Before you go

  • E-cigarettes and vapes are illegal in Thailand. You can get a large fine.

Mobile data in Thailand

  • Fast 4G and 5G in Bangkok, Phuket, Chiang Mai and other tourist areas.
  • Coverage is good on most islands, but it can be weak on small remote islands and out at sea.
  • Your eSIM connects as roaming on local networks, so turn on Data Roaming for it when you land. There are no extra roaming charges.

Useful apps

  • Grab: rides, taxis and food delivery
  • Bolt: low-cost rides in Bangkok, Phuket and other areas
  • LINE: the most used messaging app in Thailand; many hotels and shops use it
  • Google Maps: directions and places

Good to know

  • The Tourist Police (1155) speak English and help visitors.
  • Book rides in Grab or Bolt to see the price before you go and avoid haggling.
