Why buying a sim card for Thailand

best thailand sim card

Traveling in Thailand is easy with so many travel agencies, trains, boats, busses, cheap domestic flights in Thailand and uncountable affordable hotels, good food on every street corner and even fast and free WiFi everywhere. Then why do you need a Thailand sim card?

Can you imagine a life without being connected. Have you tried it before? Not being able to open Google Maps for directions, unable to order an Uber, find a nearby restaurant. Life is just so much easier and definitely when you are somewhere new and not familiar. Also in case of emergencies when your bank card isn't working, all these kind of things. Simply stay connected, it will make your trip to Thailand much easier.

Overseas data roaming plans limit your speed, did you know that? And why pay $5 per day when you get 10 GB data in Thailand for $5? Forget about roaming charges! Buying a prepaid sim card and installing it takes just a couple minutes and you are all set with the fastest 5G network connection and a lot of data for little money!

Keep in mind that a Thailand sim card will only work in an unlocked phone! So make sure your phone is unlocked when you travel to Thailand if you want to use a local prepaid sim card. If you are not sure about this contact your provider in your home country!

My recommendation

Traveltomtom recommends a True Move sim card for traveling in Thailand. They have an amazing 4G/5G network, same as with AIS, but a True Move sim card is slightly cheaper than an AIS prepaid sim card.

However, the easiest way to stay connected when traveling to Thailand in 2023 is an e-sim card. And e-sim cards for Thailand are amazing deals. If you are looking for a sim card for traveling in Thailand with unlimited data then you definitely want to hear about e-sim cards. An e-sim card for Thailand for 8 days with unlimited data already starts from $9.90 USD.

Arrive prepared for your trip and order a sim card for Thailand online. Get a prepaid sim card shipped to your home address or buy an e-sim card for Thailand and arrange everything within just 2 minutes. Right here, right now.

Where to buy a sim card for Thailand

Bangkok Airport or other international airports in Thailand

No matter which country you are travelling to a SIM card at the airport is always a little more expensive! But well worth the couple bucks as you will be online in no time! Every international airport in Thailand has official DTAC, AIS and True Move stores at arrivals. Check the exact locations below:

  • Don Mueang International Airport Bangkok (DMK): Arrival Floor, between Terminal 1 and 2, also at International Arrivals Hall between Exit 2 and 6.
  • Phuket International Airport (HKT): International Terminal 1st floor.
  • Samui International Airport (USM): Arrival Hall 1st floor.
  • Mae Fah Luang, Chiang Rai International Airport (CEI): Passenger Terminal 1st floor between Domestic Hall & International Arrivals Hall.

Are you flying to BKK Suvarnabhumi International Airport in Bangkok then check out my complete guide for buying a sim card at Bangkok Airport BKK.

Official retail stores

Wherever you go you will stumble upon a DTAC, True Move or AIS store. Just go to Google Maps and find the nearest store, there are uncountable!. Data plans will be explained very well, English is spoken, prices are fixed and they will activate it for you on the spot within a couple minutes. Every shopping mall in Bangkok, Phuket, Chiang Mai, Krabi and Koh Samui has mobile phone shops.

Convenience stores: 7Eleven, Family Mart, Tesco

Thailand sim card 7eleven

In Thailand you can buy a sim card at mostly every well known convenience store: 7Eleven only sells, DTAC and True Move. Family Mart and Tesco also sells AIS. But it is NOT as convenient as it may seem!

The hard thing about buying a Thailand sim card in a convenient store is to find someone who can really help you activate your prepaid data package! People working in convenient stores speak ok English, but mostly not enough to help you out.

Traveltomtom does not recommend buying a Thailand sim card in a convenience store! As there is no service agent to help you, you have to activate it yourself basically and packages are mostly displayed in Thai language. Good luck! :)


Buying a prepaid sim card in Thailand always be the cheapest way to stay connected when traveling to Thailand, but things have changed. You can already buy an e-sim card for Thailand for less than $10 USD with unlimited data for 8 days. Perfect for a short trip to Thailand.

If your phone is not compatible for an e-sim card then you can also order a physical sim card for Thailand online. These international sim cards for Thailand will be shipped to your home address and are automatically activated when they connect the first time to the network in Thailand. You arrive prepared in Thailand and as soon as the plane lands you have data on your phone.

Free sim card for Thailand

They often lure you with a free sim card for Thailand and even hand them out at the airport in Bangkok or when you fly Thai Airways, but remember nothing is for free! These free Thailand sim cards are just a gift but there is hardly any credit on it and when putting them in your phone they tell you straight away to top up.

If you fly to Thailand with Thai Airways they hand out free DTAC Thailand sim cards for tourists to all passengers. The sim card package says free 8 GB data, but that is NOT true, in fact it is only 20 MB. Basically 30 seconds of internet! If you want the 'free 8 GB' you first need to top up.

Registration process

Years ago you could easily buy a prepaid sim card in Thailand without any form of identification, but that all changed. If you buy a prepaid sim card in Thailand you need to bring your passport. A copy of your passport will be taken in the sim card store and your new Thailand sim card will be registered on your name and passport number. You can register up to 3 sim cards on your passport.

The sim card you receive you have to put in your phone and if your phone does not have the dual sim option you have to take out the sim card for your home country. You will get a new phone number starting with: +66.

Unfortunately they Thai mobile internet operators do NOT offer e-sim cards for prepaid plans for tourists. E-sim cards for Thailand can only be ordered on the internet.

If for some reason you want to avoid the registration process then look into buying an sim card for Thailand on the internet. E-sim cards for Thailand as well as international prepaid sim cards for Thailand do NOT require registration, they only require an email address.

Mobile internet providers in Thailand

There are 3 major internet operators in Thailand: True, DTAC and AIS. They all sell prepaid sim cards for tourists and you can buy them pretty much everywhere. However, Traveltomtom recommends buying a sim card in an official retail store. More about this later.

Back in 2014 when you were you planning a Thailand Island hopping adventure I would tell you NOT to choose an AIS prepaid sim card. Now in 2023 the table are turned and AIS has the best 4G/5G network in Thailand.

All Thailand mobile internet providers have great network coverage all over the country, even at off the beaten path places.

Mobile Internet Speed Thailand

It is no wonder that the fastest mobile data is provided by True Move and AIS. DTAC's 5G signal coverage is poor compared to its competitors. Whenever you are traveling to Phuket, Koh Samui, Krabi, Chiang Mai, Koh Tao or Bangkok or any other major tourist destinations in Thailand you will be pretty much be able to enjoy fast mobile internet with any of the mobile internet providers.

That said, when buying a sim card in Thailand it is very much recommended to ask your provider at which data speed the sim card deal operates. Some have max 5G speed (100 Mbps), but also many sim card deals are capped at 4 Mbps or 10Mbps. You see the major difference?

Anyway data speed always depends on your location and time of the day. During peak hours when everyone is online, data speed is of course significantly slower than during the middle of the night when everyone is asleep.

dtac thailand prepaid sim card

DTAC offers 2 prepaid sim card deals for tourists and although it says unlimited data, don't be fooled! Yeah unlimited on E network speed. I call this false advertisement as it was really hard to find out, but again it is NOT unlimited data!

True Move

true move h thailand prepaid sim card

There are 2 different True Move H prepaid sim card deals:

  • unlimited social media apps (Instagram, FB, Twitter, Whatsapp, Snapchat, etc*) = 49 THB ($1.5)
  • 20 GB data (4G speed)** = 120 THB ($3.7)

*Youtube and Tiktok are not included. **20 GB at 4G speed and then unlimited at E-network speed (useless).

Having free social media apps for 30 days for just $1.5 is of course insanely CHEAP!

For using Safari, Chrome, Google Maps, Uber, etc. you will need to top up. These are the 5G data pacakges:

  • 5 GB data for 30 days = 199 THB ($6)
  • 30 GB data for 30 days = 399 THB ($12.2)

Best sim card for Thailand in 2023

After my comparison of the Thailand prepaid sim cards I come to the following conclusions:

  • DTAC has by far the weakest 5G network.
  • AIS keeps it simple at has no data speed limits.
  • AIS is the most expensive.
  • True Move has data speed limits and it is unclear when you get 4G and when 5G data speed.

Taking everything in consideration Traveltomtom recommends a True Move H prepaid sim card for Thailand. You will get free social media apps for 49 THB and when you then add another 5 GB data you are pretty much set for 30 days for a total price of $7.5 USD or for 30 GB data you pay a total of $13.7 USD for 30 days.

The best prepaid sim card for Thailand in 2023 is AIS! Their sim card deals are slightly more expensive than True Move and DTAC. However, for basically everything unlimited you pay $38 USD. If you buy the same AIS prepaid sim card deal at Bangkok Airport you pay $50 USD.

For short trips to Thailand it is worth getting an e-sim card for Thailand with unlimited data for 8 days.
