Where can I buy a SIM card for Thailand?
If you’re planning to purchase a physical SIM card, then you’ve got two options: buying online before you travel or purchasing a SIM after landing at your destination.
Buying a SIM card for Thailand before you arrive
Travelers can buy a SIM card for Thailand from online stores, like Amazon. Providers offer a variety of SIM cards via the ecommerce platform that are tailored for tourists, allowing you to choose one based on your specific needs.
Buying a SIM card ahead of time removes the hassle of finding a data solution when you land, but you’ll have to pay for shipping and handling for the convenience.
You also run the risk of the SIM arriving after you’ve left for your trip—which isn’t much use when you need it to get connected. Consider these pros and cons when making your decision.

Buying a Thailand SIM card upon arrival
You can also opt to purchase a SIM card once you’ve arrived in Thailand. If choosing this route, you’ve got two main purchase points to consider:
Airports
SIM cards are available at kiosks in major airports, allowing you to get connected shortly after you land.
However, you’ll be paying airport prices—which are typically higher than elsewhere. It’s convenient but pricey.
All three of the top SIM card providers for Thailand (which we dive into further down in the article) have a presence in Suvarnabhumi Airport (BKK), the main airport in Thailand.
You can find AIS, TrueMove H, and dtac kiosks and stores near the luggage belts and baggage claim area.
You can also find larger counters for each of these providers in the arrivals hall once you’ve grabbed your bags and exited the baggage claim area.
All of these counters have signage indicating that you can purchase a Thai SIM card, so you won’t find it hard to spot them.
Local shops
You can also purchase SIM cards from local convenience stores (like 7/11 and Lotus Express) and mobile phone shops (from the aforementioned providers: AIS, TruMove H, and dtac) in the city.
However, purchasing from these outlets means you’ll be without an internet connection from when you disconnect from airport WiFi to when you find a SIM provider and plan.
Staff in local stores are also less likely to speak English, so you might need to brush up on your Thai if opting to buy local.

How much is a tourist SIM in Thailand?
The prices of a Thailand SIM card for tourists are typically between ฿50 THB to ฿600 THB (approximately $1.50 to $18 USD), depending on the package and data plan.
These usually include 1-10 GB of data with a validity of 7-15 days — with some including local calling minutes.
Best SIM card for Thailand
Before purchasing, compare data, calling, and SMS packages from different carriers to find the best option for your Thailand trip. Consider your travel length, data usage, and device compatibility.
Don’t forget to look into the provider’s coverage and network reliability, too.
Major providers in Thailand offer strong services in urban areas and popular tourist destinations, but if you’re planning to venture off the beaten path, it’s best to verify the network strength in those areas ahead of time.
