Tips For Buying a SIM Card in Thailand as a Tourist
- If your phone supports ESIM then I recommend downloading a Thailand ESIM or International ESIM.
- Never buy a SIM card which is marked as a ‘Thailand Tourist SIM’. The price for these Thai SIM cards is more than double the local rate.
- Never buy a SIM card from 7-11 in Thailand. 7-11 has an exclusive deal with True Mobile and it’s the most expensive SIM you can buy in Thailand.
- Try to avoid buying a SIM card at the airport, but if you really have to you should order in advance from Klook or Drim.

Order a Thai SIM Card to be Delivered Before You Travel - AIS is the best network in Thailand for coverage in tourist areas and also has the fastest 4G and 5G speeds. Try to buy an AIS Thai SIM card when possible.
Which is The Best Thailand SIM Card For a Tourists
It’s actually a pretty simple question “Which SIM Card is best for tourists in Thailand” and it comes down to one thing. How long you’ll be staying in Thailand?
For trips lasting 30 days or less, the best Thailand SIM Card is going to be the Airlo Unlitimed Data Thailand E-SIM.
For longer trips which last longer than 30 days, you’re best to pick up a physical AIS Thailand SIM Card(49THB). Unlimited data packages can be purchased using the AIS Mobile App.
Can I Buy a SIM Card in Thailand
Foreigners can buy SIM cards in Thailand. But the seller will need to register it to your passport. They’ll take a photo of your passport and a photo of your face too. It might seem odd, but it’s perfectly normal.
Thailand SIM Card With Unlimited Data
Thailand’s E-SIM Card packages all (technically) offer unlimited data. But be sure to check the small print- usually, the unlimited data will be at max speed until you hit a data cap (around 30-60 GB) the speeds will often be reduced after using the first 60GB.
The only option to have a genuine unlimed data plan in Thailand is to use the AIS network. Picking up a physical AIS SIM card within Thailand is necessary.
An ESIM is ideal for shorter trips when convenience is key. But an Unlimited AIS SIM is best for anyone who consumes a lot of data- streaming, for example, is staying long-term in Thailand, or working online.
Thailand E-SIM or Physical SIM Card – How To Choose
It’s 2025 and the days of the Physical SIM card are numbered. It’s now easier than ever to download a new SIM Card right to your phone. A Thailand E-SIM is a fantastic choice if your phone is compatible. It’s even possible to get set up before arriving in Thailand. Meaning there’s no messing around when you touch down. Switch-Off Airplane mode and you’ll have data instantly.
Reasons to Choose an ESIM in Thailand:
- Choose Thailand ESIM Card if you’re staying in Thailand for fewer than 30 days.
- Choose a Thai ESIM if want to save yourself the hassle of arranging a Thai SIM Card on Arrival.
- Choose an E-SIM Card if your trip is going to include other countries in South East Asia.
- Buy/Download a Thailand ESIM Card here.
Reasons to Choose a Physical SIM in Thailand:
- Choose a Physical SIM if you’re staying over a month in Thailand
- Choose a physical SIM if you want to have a lower price.
- Choosing a Physical Thai SIM Card to have an unlimited data plan.
- Choose a Physical SIM if your trip is only to one country.
- Choose a Physical (AIS) SIM if you’re visiting remote areas or remote National Parks.
iPhone models including the iPhone 11 onwards are all compatible with Thailand E-SIM Cards. Samsung Galaxy Phones from the S20 onwards are compatible with the Thailand E-SIM.

Choosing The Best Thailand Tourist ESIM
Downloading the SIM right to your phone in a few minutes makes it easier than ever to get online.
I’ve tried and tested a whole bunch of Thai ESIM Cards and International ESIM Cards. Settling on two companies as my favourites. These are DRIMSIM and AIRALO.
- AIRALO UNLIMITED DATA THAI ESIM CARD (RECOMMENDED FOR SHORT TRIPS)
This unlimited data Thailand E-SIM costs 20 USD to download and is valid for two weeks. There is a one-week plan for 10 USD. Both the 4G and 5G networks can be used. Note: This SIM is marketed as unlimed however there is an initial 30GB of data at max speed and the speeds are reduced once the first 30GB has been used. - AIRALO AISALINK 50 GB ESIM CARD (RECOMMENDED FOR MULTI-COUNTRY TRIPS)
The Aisalink is another SIM option offered by Airalo. It’s a little more expensive costing 100 USD for 50 GB of data or 185 USD for 100GB of data. But the SIM card can be used in Thailand and also any other southeast Asian county it is a good choice for multi-country trips. (Download it here)
The Best Network in Thailand for a Tourist to Buy a SIM Card
12 Months of unlimited data for a one-off payment
1,900 THB ($40USD)
There are three networks in Thailand to choose from, these are AIS, DTAC and TRUE. AIS has the fastest network speeds, the lowest prices and the best coverage in touristic areas.
Thailand’s National Parks have an exclusive deal with AIS to install cell towers in rural locations. Using an AIS Thai SIM Card I’ve picked up a signal on the top of a mountain, and on remote uninhabited islands. My girlfriend who uses DTAC often relies on using my hotspot when in rural areas.
- AIS
AIS have the best download speeds and widest coverage for both 4G and 5G including remote areas and islands. AIS is also the cheapest service provider to buy a Thai SIM Card from. But the most important reason for me is to have a no-catch unlimited data plan. AIS is the only network to offer a full ‘no-catch’ unlimited Thai SIM Card plan.
- DTAC
DTAC is the biggest competitor for AIS. And if you are in the cities and built-up areas DTAC works fine. But DTAC has limited service on the islands in the south of Thailand and in National Parks. This means DTAC is not an ideal choice for tourists moving around Thailand.
- TRUE(MOVE)
True has an exclusive deal with 7-11 where they heavily market their ‘Tourist SIM Cards’. Never buy a SIM Card from TRUE or from 7-11 in Thailand. This network has poor 5G connectivity, and poor coverage. The cost to buy a Thai Tourist SIM in 7-11 is crazy expensive. Buying 3GB of data from 7-11 costs double what AIS charge for 30 days of unlimited Thai data. Unfortunately, the Truemove Tourist SIM is the network most tourists will end up using.
What If You Phone is Network Locked
If your phone is SIM locked to a carrier in your home country then buying a SIM Card in Thailand is not going to be an option. You can try contacting your network and request the handset to be unlocked but in most cases, they will require the contract to be paid in full to do this.
Another choice is to buy a second cheap phone for your Thai SIM Card and you can use this phone as a mobile hotspot device to bring data to your main phone.
Pocket Hotspots are another option if your phone is network locked. Pocket Hotspots devices can be rented at Bangkok or Phiket Airport for 200 THB per day the price included unlimited data up to five devices can connect at once.
Using A Thai Tourist SIM As A Mobile Hot-Spot
The great thing about the data plans offered in Thailand is that you can use your unlimited data to power up other devices. I travel with my laptop, spending a lot of time working on my online businesses and writing my travel blogs, so it’s essential for me, that I have strong internet on all my devices, wherever I am.
Thai Tourist SIM Cards Speeds And Coverage
Here is a speed test, which I have run personally. Using AIS as a hot spot on the 4Mbps plan, download speeds were over 25Mbps! Which is incredible.
Choosing The Best Physical Thailand SIM Card
Listen up because I’m about to share with you the ultimate data deal for a Thai SIM Card. Thai Networks do not want tourists to know about this deal! And (unless you are Thai) you will not find this information anywhere else. To get the best deal you’ll want to buy an AIS Thai SIM Card and then buy the data yourself.
This deal is not as convenient as using an ESIM. But by following this guide you can have fast and unlimited data in Thailand for as little as 20 USD, well worth it.
Here Are The Prices For Unlimited Data Using a Physical AIS SIM Card:
| AIS 5G UNLIMITED PLANS | One Week | One Month | Six Months | One Year |
| 1 Mbps | 120 Baht | 350 Baht | 1,200 Baht | – |
| 4 Mbps | 220 Baht | *650 Baht | 1,400 Baht | – |
| 6 Mbps | 270 Baht | 850 Baht | *1,800 Baht | – |
| 10 Mbps | 330 Baht | 1,100 Baht | – | *1,900 Baht |
Remember these deals will NEVER be offered to you in person, you’ll have to buy a basic SIM card, top-up yourself and buy a data package using the app. If you’re buying a SIM card pre-loaded with data, you’ll be charged the tourist price, paying about 100 Baht per GB!
*The prices listed and in the app do not include Thailand’s 7% V.A.T. So when you top up make sure you take into account this 7% unlisted cost. So for example the 650 baht package will actually cost you 695 Baht, still, a great deal, although a little misleading.
How To Buy and Set up a Thailand SIM Card The Local Way
1) Get Yourself An AIS Thai SIM Card
Buy an AIS SIM card. They are sold in independent stores all over Thailand. Phone Case Merchants and Phone Repair Shops will sell AIS SIM Cards. Malls such as MBK in Bangkok too and sometimes travel agents.
Do not buy the SIM cards branded with ‘Thailand tourist SIM’. Do not buy a data package from the seller.
You need to buy a basic SIM Card and nothing more. Standard AIS SIM Cards cost 49 THB.
2) Connect To Wi-Fi
Your AIS SIM Card should be inside the phone now. But without a data package, you can’t do much, yet.
To buy a data package, you’ll need to download the myAIS application and top up your new SIM. Wi-Fi is easy to come by in Thailand find a connection at a hotel or restaurant and download the AIS application. To register all you need is your phone number. Once the app is downloaded navigate to the menus and click on the ‘Add a new package’ option where you can select an unlimited data plan. But first, you’ll need to top up.
*You can set the language of the APP from Thai to English in the top menu.
3) Top Up Your AIS SIM
You can top up directly from the application itself, paying with your debit card. Or at an ATM you can even top up using cash! select the ‘Mobile Top Up’ option on the ATM menu and choose AIS 1-2-Call then key in your phone number and insert the amount of cash you want to top up into the slot when it opens. The funds will be credited to your account and reflected in the ASI app instantly.
4) Buy Yourself An Unlimited Data Package
Once you’ve loaded your phone with $20 credit (1,000THB) and set up the network application (myAIS), open the app, hit the package button, and then the ‘Apply Internet On Top’. Click on the ‘Internet non-stop tab’ which is where you’ll find all the unlimited data plans. And yes, these plans are actually unlimited! Use it as a hot spot, or for streaming and never worry about your data getting used up.
You have a selection of internet plans based on connection speed and the length of the package. In my opinion, the 4mbps package on a 30-day plan is the best value for money at 650 Baht ($20), but if you need higher internet speeds or a longer plan there are options for you! If you are staying in Thailand longer than a month then for 1,800 Baht ($55) you can get six months of unlimited, max-speed internet. Now that’s a good deal!
NEW ONE-YEAR SIM DEAL 2025
AIS has launched a new deal which is the best value for money you can find in Thailand. This Deal can only be purchased in an AIS store in Thailand (not at an AIS Kiosk or Airport Kiosk).
The AIS Super Premium Gold SIM includes a V.I.P. phone number and gives 100GB of data every month for one year. The data rolls over and the download speeds are not capped. This package has an insanely low price, a one-off payment of 1,900 Baht (55US) lasting 12 months! You’ll have a whopping 1.2TB of data to use over the year.
So that’s everything you could ever need to know about buying a SIM Card in Thailand as a tourist. With a ton of choices, you can avoid being ripped off with a Thailand Tourists SIM Package.
With your Thailand ESIM, all set up you’ll have plenty of data to browse through the rest of my blog 😛 There’s so much useful content about Visiting Thailand right here. But here are some of my favourite Thailand travel articles to get you excited about your trip!

Great information. However your link , you can pre-order a SIM card for collection here. to Klook only seemed to offer some sort of WiFi Device. I’ll be arriving Bangkok and will need to order a Bolt but will need a Sim to register on Bolt again. Like your idea of AIS Sim as I have been ripped with expensive Tourist SIMs on previous trips.
Hey did anyone ever try to convert the physical AIS sim to an esim and if so can you still make use of all the deals mentioned above of a physical sim in the AIS app?
This has been the clearest post I have found on sims in Thailand. Thank you! I’m going to Thailand in a couple of weeks and I have my AIS sim from last year. When I bought it, it was a 30 day package but I’m thinking I might be able to use it again and just top up or will the sim be “worthless” because I can only use it for the 30 days specified last year? Any ideas?
Hey 🙂 AIS SIM Cards will expire if they are inactive for 365 days. So, if it has been less than a year, you can just insert it into a phone, and use the myAIS app to buy a new data package. If it’s not been used for a year you need to replace the SIM — the official price to buy a new SIM without a package is 49 Baht — but in tourist spots prices are often around 100 -200 Baht.
Thank you for such a descriptive and updated post! I do have one question, though. I want AIS as my provider. But I saw that one can also get an AIS eSIM card (50GB/30d/850THB). Should I expect any difference in coverage between an AIS physical SIM or an AIS eSIM?
Hi 👋 You’re welcome. AIS is the best choice for most people. There is no difference in coverage between ESIM and Physical SIM — that being said — I’d opt for a physical SIM if you have the choice. The deal you mentioned seems reasonable, but I do recommend downloading the official AIS App and double checking the prices on there before you commit to anything — to make sure you get the best deal.
I wish you described a bit in more detail what the 2mbps through 10mbps speeds actually mean in an unlimited plan. You mentioned 4mbps as the recommended speed.
Isn’t 4 really slow? I mean I am getting like 150mbps with 5g where I am right now.
Hi there, are those Informations actuel in 2023?
Hello, yes I keep this page updated annually- with the latest deals, usually at the same time I renew my Thai phone plan 😅 To shorten the article, it you in Thailand for a short trip (two weeks or less, then download an ESIM). If you are here for any longer than that, it’s best to pick up as AIS SIM locally and buy a date pack from the MyAis app.
Hey, that’s an…… awesome deal. I’m definitely getting it in the next few months when I will most likely be one of “guinea pig” tourists in Thailand.
Last time I was there I fell for the airport scam – but at least took a bus instead of a taxi!
Anyway, do you have any experience with getting an AIS esim as a foreigner? Would have been more convenient for me, so I wonder if that’s an option.
Cheers.
