Thailand

Useful apps for Thailand: transport, maps, translation

Install four apps before you fly: Grab or Bolt for rides, Google Maps for navigation, LINE for messaging shops and drivers, and your bank's card app with travel notifications on. Add a translation app if you leave the tourist trail. You need a Thai number only for some public Wi-Fi and local wallets, not for the core four.

Details

Set the phone up before you land, not in the arrivals hall on airport Wi-Fi. Download offline maps for the provinces you plan to visit, add a payment card to Grab or Bolt, and turn on travel notifications in your bank app so a blocked card does not strand you at a hotel desk.

Ride-hailing is the single biggest quality-of-life app in Thailand. Grab and Bolt both cover Bangkok, Chiang Mai, Phuket and most tourist towns; Bolt is often cheaper, Grab has more drivers and food delivery. Fares are metered through the app, which removes the negotiation that catches first-time visitors. At airports, use the designated pickup zone rather than the kerbside taxi rank.

Google Maps handles turn-by-turn driving, bus and boat routes in cities, and walking directions that are usually good enough. It is weaker in rural areas and on smaller islands, where a downloaded offline map plus a screenshot from your hotel helps. Street View is patchy outside the main cities.

LINE is how Thailand actually communicates. Hotels, tour desks, drivers and small shops use it for bookings and confirmations, so a free account with your home number is worth having. WhatsApp works but is mostly used with other foreigners.

Translation: Google Translate's Thai offline pack and camera mode cover menus and signs. For spoken Thai, expect mixed results; a screenshot of your destination in Thai script is more reliable than voice input.

Money and connectivity apps matter too. Thai QR (PromptPay) is accepted almost everywhere but needs a Thai bank account; some tourist e-wallets and foreign cards can link to it — check before you rely on it. AIS and TrueMove H sell tourist SIMs at airport arrivals with passport registration, and eSIMs work on unlocked phones with 5G in cities and 4G on most islands.

Tips

Download offline maps and the Thai language pack on home Wi-Fi before departure; airport data is slow and metered.

Screenshot your hotel address in Thai script. Drivers and front desks read it faster than an English pin.

Keep one ride-hailing app as backup. If one has no cars in a downpour, the other often does.

Public Wi-Fi in malls and cafés is generally fine for browsing; avoid banking on open networks and use your mobile data instead.

Most apps and sites work in Thailand; gambling and some political sites are blocked, and a VPN works if you need one.
