Almost every tourist that travels to Thailand wants to buy a Thai SIM card, but which one? If you did not gather some information before your trip you are relying on the sales guys at the airport. Can you trust them? Nope! So here is your guide to what is the best Thai SIM card for travellers.

Why buy a Thailand tourist SIM?

Travelling in Thailand is fairly easy nowadays with so many tourists agencies around. A place to sleep can easily be found, good food is always around the corner and transportation can be booked in every street. Then why do you need a Thai SIM card?

First of all to simply be online. I am an internet addicted and I should be, as a blogger I constantly want to be online. For me it is not just a way of keeping in touch with my family and friends it is work as well. So a travel sim is vital!

But even if you are not an internet addict it is handy to have a Thai SIM card. Think about emergency situations, meeting up with fellow travellers or using Google Maps to find directions. It makes travelling so much easier and it is really affordable! If you are not a fan a changing your SIM card, then Teppy is probably something for you!

For example I always buy 4.5 GB data package 4G speed for $12 valid for 1 month. Calling rate is 1THB per minute, which is $0,03, which provider? Read down below and find out what I think is the best sim card for travelling in Thailand.

What is the best Thailand tourist SIM card

Are you planning to go to remote areas in Thailand? Are you island hopping in Thailand? Do you want a 4G internet connection? Different types of travellers and different types of SIM cards, find out which one suites you most.

There are 3 major suppliers in Thailand: True, DTAC and AIS. All of them have pros and cons, but their signal and 3G coverage is nowadays everywhere the same. So if you are going to the major touristy spots and you are not interested in 4G internet speed then simply choose the cheapest option of one of these 3 mobile companies. You will signs everywhere saying: 'Thailand SIM card for tourist'.

For travelling up north to places like Chiang Mai it only depends if you want to be connected to 4G or not. All providers have reliable coverage, though only True has a big 4G network in these areas, the others do not!

Are you planning to go island hopping in Thailand and still want to be connected to the world then do not choose AIS, their coverage on remote islands can be shit. DTAC is the SIM card you want for island hopping in the South of Thailand as they have the best coverage on islands.

For the fastest internet you should get a SIM card of AIS, as their speed is by far the best, see the chart down below. Although their internet speed is very fast, their 4G coverage is very bad, see the maps. But staying in places like Phuket, Samui, Chiang Mai and Bangkok only, you should choose AIS.

If you are just like me addicted to the internet and 3G is not good enough anymore than True Move is your provider. They provide the best 4G coverage in Thailand, see the maps down below.

Heading to a specific area then go to and zoom in on your destination to find the best provider. Especially for long term travellers this tool is perfect to see what is the best thai sim card for nomads. The perfect example is myself. I know I was going to live in Koh Tao for 6 weeks, so I zoomed in. The fastest internet is provided by AIS, True has the biggest 4G network, but I chose DTAC. Why? DTAC is the only provider offering 4G in Koh Tao! 

I did my PADI divemaster training on Koh Tao and lived there for several months. Looking for cool things to do in Koh Tao? Check out my blog: top 5 things to do in Koh Tao. Heard bad stories about Koh Tao in the news? We all did!

Planning to stay for longer than a week in Thailand then head to a phone shop rather than the 7Eleven. Prices drop for monthly plans, but they don’t sell them at the 7Eleven. In Thailand the golden rule applies as well: do not buy a bangkok airport SIM card, but buy your SIM card in Bangkok itself! No matter which country you are travelling to, never buy a SIM card on the airport as they are always rip offs compared to what they offer in the city. They often lure you with free SIM, but remember nothing is for free especially in touristy countries in South East Asia! ;)

Some countries like the USA seel 'locked' iPhones and therefore buying an international SIM card is not an option. Or may be you are not convinced exchanging your SIM card for a Thai SIM card. In these cases I recommend you to take a look at Teppy a portable WiFi for smartphones, laptops and tablets. It is a very convenient and reliable internet source while traveling and sometimes easier than going all the way and buying a new SIM card and getting a new phone number.
