So, whether you’re a short- or long-term traveler, you can save money by comparing your SIM card options on finder.com.
There are three main telco providers in Thailand: AIS, dtac and TrueMove H. Locals and travelers use SIM cards from all three networks, and they can be trusted no matter which plan you choose. According to OpenSignal’s coverage map, the main cities, highways and urban areas offer great network coverage, while the more remote areas can sometimes lack a good signal.
All operators offer prepaid SIM cards, and you can buy them from stores, supermarkets, kiosks, drug stores and official outlets as well as at the Suvarnabhumi, Don Mueang and Udon Thani international airports. 2G, 3G and 4G plans are available on all networks for unlocked GSM phones. You can buy a SIM card by showing your passport, and your telephone number is already active when you purchase it. To add credit, there are several prepaid card machines around various towns and cities, and vouchers are stocked in corner stores and supermarkets.

While it’s well known for reviews, booking hotels, flights and vacations, TripAdvisor also has many user comments that can help guide you through what SIM cards have been tried and tested in Thailand.
“You can get a basic SIM for free at the airport, but it’s better to buy a data/calls package from one of the big three, which all have booths in the arrivals hall. AIS, DTAC, TrueMove. Usually, after the card is put in the phone, you wait a very short time and you’ll get a welcome SMS telling you the service is activated. The staff will help you.“
“The operators have special tourist SIM packages which are easy to buy but you may find it difficult to extend their validity past the standard validity period (typically 7 or 15) days. This would be inconvenient if you want to keep the same number for repeated visits.“
“They can sell you the appropriate SIM given your needs… Just make sure your phone is “unlocked” and can accept a Thai SIM as these shops don’t do any ‘servicing’ of phones.”
