Why buy a sim card in Thailand

best thailand sim card

Traveling in Thailand is fairly 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 new somewhere and are 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 Thailand. They have an amazing 4G/5G network together with AIS, but a True Move sim card is much more affordable than an AIS prepaid sim card.

If you want to be prepared before your trip then order a sim card for Thailand online and get it shipped to your home address or buy an e-sim card for Thailand.

Unmistakably the best way to get internet when traveling in 2022 is an e-sim card! No need to swap sim cards, go to a store or activate data packages anymore.

Mobile internet providers Thailand

There are 3 major suppliers in Thailand: True, DTAC and AIS. If you are visiting the standard tourist destinations in Thailand you are going to be covered with a very strong 4G/5G signal.

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 2022 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.

However, DTAC is really staying behind when it comes to upgrading their 5G network. It is difficult to say who has the best 5G network in Thailand. It is a very close call between AIS and True Move H but AIS has the most extensive and strongest 4G/5G network in Thailand.

Best Thailand prepaid sim card in 2022

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 in Thailand in 2022 is AIS, they are however also much more expensive than True Move and DTAC. For basically everything unlimited you pay $38 USD.

Where to buy your Thailand prepaid sim card

Buying a sim card at Bangkok and 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:

  • Suvarnabhumi International Airport Bangkok (BKK): International Arrivals Terminal 2nd Floor and International Arrivals Hall around Baggage Claim No. 18.
  • 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.

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, 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.

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.

Convenient 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 that 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! :)

What to bring if you buy a sim card in Thailand?

Years ago you could easily buy a sim card in Thailand without any identification, but nowadays they changed a couple rules. If you purchase a sim card in Thailand they will need your passport. Still street vendors sell prepaid data packages without any identification needed, but the official resellers will need your passport. So always bring your it when you are going to buy a sim card in Thailand. They will take a copy in the store or take a photo of it for their administration.
