Mobile data and tourist SIM cards in Thailand

In Thailand your mobile data travels over three big networks: DTAC, AIS and TrueMove H. The plan roams on these, so your phone picks whichever signal is strongest at the time. Coverage is usually good in Bangkok, Phuket, Krabi and Samui. It is weaker in national parks, the northern mountains and small remote islands, so download offline maps before a boat trip.

Data earns its keep when you are getting around. Grab lets you book a taxi and see the fare up front, Google Maps handles routes and a translation app helps with menus. Many Thais use LINE for messaging, and tour operators and guesthouses often expect you to reach them there.

You can buy a tourist SIM card at the airport, but that means queuing, registering your passport and swapping cards on arrival. With an eSIM the setup is already done at home and your own SIM stays in the phone alongside it. The plan is data only, so calls and texts go through WhatsApp or a similar app.

FAQ: Thailand

Does mobile data work on the Thai islands, such as Phuket and Samui?

On the big tourist islands like Phuket and Samui coverage is usually good. On small islands and on boat trips the signal can drop, so download maps and tickets to your phone beforehand.

Which is better in Thailand, an eSIM or an airport SIM card?

An eSIM is easier if you want data straight away and want to keep your own number in the phone. An airport SIM means a queue and your passport, and its main advantage is a local phone number.

Will Grab and Google Maps work on a Thailand eSIM?

Yes, they run over the data connection just as they do at home. For Grab, install the app and sign in before you travel.

What can I use this eSIM for?

The plan is meant for mobile internet on your trip, for example maps, messages and browsing.

Will my own number still work?

Yes. Your own number and SIM card stay active for calls and messages. Choose the Reissaa eSIM for mobile data.

When should I buy the plan?

Buy and install the eSIM before you leave, while you have a stable internet connection.

Will my own mobile plan work in Thailand?

EU roaming rules do not apply in Thailand, and data on your own plan can be expensive. With an eSIM you know the price in advance.

Do I need a travel adapter for Thailand?

Usually not. The sockets in Thailand are type A, B, C, F, O, and a European C/F plug fits most of them. Voltage is 230 V.

What is the calling code for Thailand?

The calling code for Thailand is +66. To call your home country from abroad, dial its country code and leave out the leading zero of the number.
