Which SIM card is best to buy in Thailand in 2026 for internet and calls?

The best option for most tourists is a local SIM card from one of three operators: AIS, TrueMove H or Dtac. They provide excellent coverage and fast internet throughout the country. The choice depends on your needs:

• AIS — the best choice if you plan to travel to islands or remote areas, as they have the most stable coverage in the countryside.
• TrueMove H / Dtac — a great option for cities (Bangkok, Chiang Mai, Pattaya) and resorts (Phuket, Samui). They often offer more favorable rates with a focus on social networks.

The easiest way is to buy a ready-made tourist SIM card at the airport, in 7-Eleven stores, or from guides. Prices start from 349 baht. If you want to save money and are willing to figure it out a bit, you can buy a Prepaid card (for example, at 7-Eleven) with a basic rate from 29 baht and activate the desired internet and minutes package yourself.

For those who do not want to look for a physical card, the ideal solution is an eSIM. You can buy it online before departure, for example, on Trip.com, where Russian cards are accepted. eSIM prices start from $6-8 for a 7-10 day package.
