On our multiple trips to Thailand, we have tried and tested the different options of Thailand SIMs and eSIMs to know which to recommend and which not.
So in this article, we’ll cover all the essentials you need to know about before buying a SIM card or eSIM package in Thailand.

Why you should get a Thailand SIM card
While WiFi is widely available in Thailand, in your hotel, hostel, or resort, and almost all cafes and restaurants, getting a local Thailand SIM card is the way to go for a comfortable trip.
The most significant benefit of buying a Thailand SIM card package is comfortably using ride-hailing apps like Grab (Uber), Google Maps for navigation, and Google Translate.
And while it’s true that most locals and businesses in Thailand use apps like WhatsApp and LINE for communicating, having a local number has proven helpful for us.
Since you’re reading this blog, we assume you’re not in the group that wants to explore Thailand while being “offline.” (nothing against those people – respect!)
Need reliable Travel Insurance for Thailand?
With 24/7 worldwide assistance, Heymondo insurance includes comprehensive coverage for medical expenses, trip cancellations, and baggage loss or delay.
For digital nomads or full-time travelers, we recommend SafetyWing, which includes brief visits to your home country every 3 months abroad.
Should you get a physical SIM or eSIM for Thailand?
For the last few years, it’s very common for most people to have phones supporting eSIM technology.
Buying a Thailand eSIM is the most hassle-free option, as you simply buy it online, scan the QR code you receive and install it on your phone in minutes—no need to go to any store or mess around with it at the airport.
So if your phone supports eSIMs, there’s no reason not to get one.
eSIM Compatibility
We are big supporters of the eSIM technology and have had it since we got a phone that supported it a few years ago.
Note: Many Thailand eSIM packages you can find online don’t come with any text or calls. However, our favorite, Thailandesim, does have packages that include them.
But that’s also the case with some of the standard SIM packages at the airport. Most only give you data.
So if you need calls and texts, just make sure your plan includes it (we will recommend the best packages below).
Which Thailand mobile carrier is the best?
There are four major mobile carriers in Thailand, with the two best networks being AIS and DTAC, and right behind being TrueMove, with still great coverage, excellent internet speed, and more affordable plans.
The internet coverage and speeds in Thailand are amazing, even 5G. So any of the top carriers will perform well all over the country. And if you want the clearest picture of each carrier’s coverage in Thailand, check out the practical nPerf coverage map.
1. AIS
AIS is the mobile carrier with the best coverage in Thailand and the most expensive packages. However, it’s the best choice for travelers who want the ultimate coverage and the most reliable service.

2. DTAC
DTAC has the second-best coverage in Thailand and, in addition to AIS, is the best choice for great coverage.
And DTAC also offers the famous Happy Tourist SIM Card package, which you can find all over Thailand or buy it online on Airalo.

3. TrueMove
We’ve used TrueMove the most and have had great coverage throughout Thailand, with fast internet speeds, even when we hot-spotted it for work on our laptops.
The ONE time where we would have needed to have AIS with better coverage was during our stay on the Floating Bungalows on Cheow Lan Lake in Khao Sok (AIS was the only one with signal).
TrueMove has the third-best coverage but offers many plans with high internet speeds. And that’s why it’s an excellent choice for most travelers.

Where to buy your Thailand SIM card
The three most common ways to buy your Thailand SIM card are at the airport, online, or at one of the official mobile carrier stores in Bangkok, Chiang Mai, Phuket, Krabi, or any other city.
1. Buy a physical Thailand SIM card at the airport
The simplest way to buy your physical Thailand SIM card is upon your arrival at the airport.
All Thailand airports are full of kiosks selling Thailand SIM card packages from operators like TrueMove, DTAC, and AIS.
Just walk up to the kiosk, and you will get your Thailand SIM card installed and ready to go in minutes.
We highly recommend comparing packages of at least two kiosks to find the best deal, as they don’t always offer the same packages or prices. And while some have better deals for shorter periods, some have better deals for longer trips.
Do note, though, that mobile packages at Thailand airports are more expensive than at official stores or online.
Note: Please note that to buy a physical SIM card, you need a passport, as they will have to register the package in your name, as is the official requirement. This is not required if you buy an eSIM online.
2. Buy your Thailand eSIM online
It’s straightforward to buy a Thailand eSIM online and activate it in a matter of minutes.
Getting an eSIM online is especially smart if you’re entering Thailand by land border from Cambodia, Laos, or Malaysia. If you’re on an organized bus trip, you usually don’t have enough time to sort your SIM at the border.
And, of course, having a pre-installed eSIM when arriving by plane in Thailand means that you’re online as soon as you land.
We’ve been following the providers of Thailand eSIMs since they started offering them and have compiled a list of the best ones below.
Thailandesim
Affordable, Best choice for unlimited plans
Airalo
Affordable for short and long trips
SimOptions
Great selection of eSIM and prepaid SIM plans

3. Order your physical Thailand SIM online
You can order your Thailand SIM card online and pick it up at Thailand or nearby airports or get it delivered to your home address. This way, you get a much better deal than buying it directly at the airport, and you get to skip the line.
The Thailand SIM card pick-up options are great, but the delivery options are currently a bit limited. We could only find reliable options for China and Vietnam.
Please let us know if you find any more options for delivery of Thailand SIM. We would love to update this guide and let others know about it.

4. Buy your Thailand SIM card at the official store
You can buy your Thailand SIM card at one of the official stores of mobile carriers across all cities.
Buying your package at the official carrier store of TrueMove, AIS, and DTAC can get you better deals than at airports or smaller reseller shops.
Stay protected on public WiFi
We’ve been using NordVPN for over 5 years now and can highly recommend the tool for protecting your privacy and freedom while browsing the internet.
It encrypts your connection and hides your data from potential hackers. Also, with a VPN, you can access blocked/restricted content like some Netflix movies or booking sites.

How much does a Thailand SIM card package cost?
Thailand SIM Card packages are affordable and cost upwards of 4 USD for a smaller amount of data and about 10 USD for an excellent data package with text and calls included.
Mobile data packages often change names, and what they offer, so we won’t discuss each carrier’s packages. But we will give you a reliable estimated cost of a Thailand mobile package.
| 4G DATA IN PACKAGE / VALIDITY | COST OF PACKAGE |
|---|---|
| 15 GB – 15 days | 6 USD |
| 30 GB – 1 month | 9 USD |
| Unlimited data – 7 days | 10 USD |
| Unlimited data – 15 days | 20 USD |
| Unlimited data – 30 days | 30 USD |
Please note that the prices and packages at Thailand airports can be different and often higher than what you would pay at the carrier’s store.
MORE OPTIONS
Do you get calls and texts on your Thailand SIM card package?
Most Thailand SIM card packages you can buy at the airport come with a good amount of calls and texts.
You can also top-up some money to your account and get extra calls and texts if the package you bought doesn’t include them. Calls in Thailand cost about 1 Baht per minute, and texting costs about 2 Baht per SMS.
Our recommended provider Thailandesim, also includes calls and texts with a local number in most of their eSIM packages.

How to top up your prepaid Thailand SIM package?
Topping up your Thailand mobile package is simple in almost every convenience store, like 7-Eleven.
Often, these stores have dedicated systems where you just provide them with your phone number, and they top up how much you want to your account. And if they don’t have that system, you will receive a code on your receipt that you use/call to top up.
Finally, you can buy top-up vouchers or scratch cards and simply use the codes to top up.
And don’t forget that all carriers offer mobile apps where you can register your SIM, top-up your credit, change your plan or buy add-ons.

I followed this article and bought 2. DTAC.
They have 8 minute youtube videos for installation guide it’s hell long.
Also nowhere in the process did they warn that activation policy says it starts counting on installation, and i installed it when my holiday is far out and the plan will be expired in the middle of my holiday, very bad.
The youtube also made it seem like there are 2 setup steps, one done locally before going, and other when reach destination. It misleads people into thinking the local step can be done first, and user can choose to do 2nd phase when arrive. But they actually start counting when installed locally.
Good to warn in this article.
Hi Han,
Thanks for this review of DTAC! We’ll make sure to include this information in the article.
Happy travels!
