My recommendation
Before I tell you what is the best eSIM for Thailand in 2024 check the following carefully!
Before ordering an eSIM for Thailand make sure your phone is unlocked and your phone is eSIM compatible. eSIMs only work on eSIM compatible phones that are unlocked.
Traveltomtom rates the DTAC Happy Tourist 5G as the best eSIM for traveling to Thailand in 2024.
- 50 GB data + 100 minutes for 10 days = $9.90 USD
- Unlimited data + calls + sms for 15 days = $19.90 USD
You can order the DTAC eSIM for Thailand via Airalo or SimOptions.
This DTAC eSIM for Thailand is 5G ready, where most other Thailand eSIMs only offer 4G/LTE network speed. There is a 5G signal available at pretty much all tourist destinations in Thailand.
Traveltomtom does NOT RECOMMEND eSIMs for Thailand with unlimited data, unless it is specifically specified that UNLIMITED MEANS UNLIMITED. Traveltomtom only recommends eSIMs with unlimited data if the unlimited data is on max data speed and there is no FUP (Fair Use Policy).
Be careful, many websites offer eSIMs with unlimited data, but there is a so-called FUP (Fair Use Policy) and before you realize you are browsing like on 3G data speed.
The above DTAC eSIM for Thailand with unlimited data from Airalo and SimOptions is truly unlimited! Approved, confirmed and tested by Traveltomtom!
Out of all the Thailand eSIM providers Traveltomtom recommends Airalo and SimOptions the most for buying an eSIM for traveling to Thailand. Why? I have tried both eSIM providers in more than 100 countries around the world and never had a problem.
Specifications DTAC tourist eSIM
The above DTAC tourist sim cards come with unlimited data or 50 GB data Thailand. Unlimited is truly unlimited, no speed cap, all the data is available on max data speed.
The newer versions of the DTAC eSIMs include either 100 minutes calling time or unlimited minutes in Thailand to local phone numbers. These Happy Tourist eSIMs also comes with 15 THB international calling credit.
Calling cost 0.99 THB per minute in Thailand and sending an sms cost 3 THB per sms to a Thai phone number. Unlimited calls to other DTAC numbers are included. This eSIM comes with a Thailand phone number that starts with +66. Receiving phone calls and sms is free.
The validity of the DTAC eSIMs starts immediately after installation, even if you are not in Thailand. After ordering your eSIM on the internet you have 30 days to instal the sim card and after installing you can use the eSIM for either 10 or 15 days.
Thailand eSIM comparison
On the internet you will find multiple websites that offer eSIMs for Thailand. Traveltomtom recommends ordering an eSIM for Thailand from one of the well-known eSIM providers. Above you found my first recommendation, but there are many more eSIMs for traveling to Thailand.
You can order an eSIM for pretty much every country directly from eSIM providers like SimOptions, Airalo, Nomad, Holafly, Jetpac, Sim Local, Roamless, etc. and instantly receive your eSIM in your email. But before you buy an eSIM first read all my tips below.
SimOptions also offers international prepaid sim cards for Thailand. These pre-activated physical prepaid sim cards will be delivered to your home address before your trip and it is plug and play when you arrive in Thailand.
Jetpac
Jetpac is a new eSIM provider that offers eSIMs for more than 100 destinations around the world. They also offer regional eSIMs like for Southeast Asia, Europe, Middle East, etc.
What makes Jetpac stand out from other eSIM providers is that the Jetpac eSIMs come with a bunch of benefits for example a free VPN subsription, lounge passes, etc.
Here are the Jetpac eSIM plans for Thailand:
- 1 GB data for 4 days = $1 USD
- 3 GB data for 7 days = $6 USD
- 5 GB data for 30 days = $9 USD
- 10 GB data for 30 days = $16 USD
- 15 GB data for 30 days = $21 USD
- 20 GB data for 30 days = $18 USD
- 30 GB data for 30 days = $21 USD
- 40 GB data for 30 days = $25 USD
- 50 GB data for 30 days = $10 USD
Click here for more info or to order the Jetpac Thailand eSIM.
The Jetpac Thailand plan with 50 GB data is the same DTAC eSIM plan that Airalo and SimOptions also offers.
You can instal your Jetpac eSIM before your trip to Thailand, but it only activates from the moment it connects to a supported network in Thailand or one of the other supported countries. That moment your days also start counting. The Jetpac eSIMs have to be installed within 1 year.
The Jetpac Thailand eSIMs are data-only and incoming and outgoing calls and sms are not supported. These eSIMs do not come with a phone number The Jetpac eSIMs for Thailand are all 5G ready.
An extra advantage of Jetpac Thailand eSIMs is that they provide free lounge access if your flight is delayed. However, you will have to register your flight before you travel and in case of a delayed or canceled flight a LoungeKey voucher will automatically be provided. As said it also comes with a free VPN subscription and you can buy fast track passes and lounge passes at a discounted rate in their app.
This is a complimentary service that no other eSIMs offer. For more info check the Jetpac website.
SimOptions
SimOptions is a very reliable eSIM provider. Traveltomtom has used SimOptions uncountable times in more than 50 countries around the world. I can totally recommend using SimOptions for your eSIMs.
SimOptions offers the same DTAC tourist eSIMs as Airalo plus a couple other plans, which are more expensive.
These are the DTAC eSIMs from SimOptions:
- 50 GB data for 10 days + 100 minutes = $9.90 USD
- Unlimited data, calls and sms for 15 days = $19.90 USD
Click here for more info or to order a DTAC eSIM for Thailand via SimOptions.
The DTAC eSIMs from SimOptions come with a Thai phone number starting with +66. That means you can also receive calls.
The above DTAC eSIMs make the other SimOptions eSIM plans for Thailand look bad.
- 1 GB data for 7 days = $3.90 USD
- 3 GB data for 30 days = $4.90 USD
- 5 GB data for 30 days = $7.90 USD
- 10 GB data for 30 days = $14.90 USD
- 20 GB data for 30 days = $31.90 USD
- 30 GB data for 30 days = $44.90 USD
- 50 GB data for 30 days = $71.90 USD
Click here to order an eSIM for Thailand from SimOptions.
Specifications of the Thailand eSIMs from Simoptions
All the SimOptions Thailand eSIMs are 5G ready, but it is unclear if these eSIMs use either the AIS, True Move or DTAC 4G/LTE/5G network in Thailand.
These specific eSIMs from SimOptions are data-only and do NOT support calling and texting and they does NOT come with a phone number. You can't receive calls and text on this eSIM. The credit validity starts immediately after installing the eSIM. Even if you are not yet in Thailand. APN settings are available.
For more info about the above Thailand eSIMs check out the SimOptions website.
What I like about SimOptions is thatI already used more than 100 eSIMs from SimOptions and only had to trouble shoot once or twice for a minor issue. As much as I recommend SimOptions, I don't like their Live Chat and have mixed reviews about the SimOptions Help Desk.
Check out Traveltomtom's honest review about using SimOptions eSIMs with all pros and cons.
Airalo
Airalo is very much recommended by Traveltomtom. Ordering an eSIM through Airalo is done fast and easy. Traveltomtom has used Airalo uncountable times for staying connected when traveling abroad. Very reliable, never an issue and what Traveltomtom likes about Airalo is that they specify a lot of information on their website about their eSIMs.
If you read my recommendation in the beginning you already know that Traveltomtom recommends ordering a Thailand eSIM via Airalo. For 2024 they have the following eSIM plans for traveling to Thailand:
- 50 GB data + 100 minutes for 10 days = $9.90 USD
- unlimited data + unlimited calls + unlimited texts for 15 days = $19.95 USD
Click here to order an eSIM for Thailand via Airalo.
The DTAC Happy Tourist Infinite truly is an unlimited data eSIM for Thailand without any data speed cap.
Normally Airalo sells a wide range of eSIMs per country, but for Thailand they only sell these two DTAC eSIM plans.
Specifications Airalo eSIMs
See my recommendation for more detailed info about the DTAC eSIMs for tourists. The Airalo eSIM plans from DTAC start immediately after installation.
For more info check out the Airalo website where they specify everything about their eSIMs.
Holafly
Holafly is another well-known eSIM provider but unlike other providers they only offer eSIMs with unlimited data. However, there is a catch and that is a so-called FUP (Fair Use Policy). More about it later, but it could mean that you suddenly have a very slow data connection for a whole day until it resets.
Here are the Holafly unlimited data eSIM plans for Thailand:
- 1 day 'unlimited' data = $6 USD
- 2 days 'unlimited' data = $10 USD
- 3 days 'unlimited' data = $13 USD
- 4 days 'unlimited' data = $16 USD
- 5 days 'unlimited' data = $21 USD
- 6 days 'unlimited' data = $25 USD
- 7 days 'unlimited' data = $29 USD
- 8 days 'unlimited' data = $31 USD
- 9 days 'unlimited' data = $35 USD
- 10 days 'unlimited' data = $37 USD
- 11 days 'unlimited' data = $40 USD
- 14 days 'unlimited' data = $48 USD
- 20 days 'unlimited' data = $64 USD
- 30 days 'unlimited' data = $75 USD
As you can see the Holafly eSIMs are significantly more expensive than Airalo and SimOptions. The Holafly eSIMs for Thailand are data-only and incoming and outgoing calls/sms are NOT supported. These eSIMs do also not come with a phone number. The Holafly eSIMs operate on the 4G/LTE/5G network of True Move
You can use a hotspot on the Holafly eSIMs, but it is capped at 500 MB per day.
Why 'unlimited'? Because there is a Fair Use Policy and Traveltomtom has had bad experiences with this in the past. Suddenly your data speed is slowed down for 24 hours because you apparently used too much data. More info later.
If I hate something then it is slow data speed. Therefore Traveltomtom's is not a fan of eSIMs with 'unlimited' data with an FUP and therefore it is not my first recommendation when looking for an eSIM for Thailand.
Also, Traveltomtom tested Holafly in another country and was very disappointed with the overall performance. Holafly was using the weakest mobile data network operator in that country and while people all around me constantly had a data connection I was pretty much offline for a whole week. Even when we were in big cities I constantly had to ask for the public WiFi of my hotels, restaurants and bars because my Holafly eSIM was super slow.
Nomad
Traveltomtom has used Nomad only a few times yet and so far so good. Tested and reviewed, Traveltomtom found Nomad to be a trustworthy eSIM provider. They sometimes have incredibly competitive eSIM plans and prices.
For traveling to Thailand Nomad has regular eSIM plans as well as unlimited data eSIM plans.
These are the regular Nomad eSIM plans for Thailand in 2024:
- 1 GB data for 7 days = $4 USD
- 3 GB data for 30 days = $11 USD
- 5 GB data for 30 days = $14 USD
- 10 GB data for 30 days = $20 USD
- 15 GB data for 30 days = $26 USD
- 20 GB data for 30 days = $30 USD
- 30 GB data for 30 days = $80 USD
- 40 GB data for 30 days = $110 USD
- 50 GB data for 30 days = $125 USD
On top of that Nomad also offers the DTAC Happy Tourist eSIM:
- 50 GB data + 100 minutes for 10 days = $8 USD
Click here to order an eSIM for Thailand via Nomad.
Nomad also sells eSIM plans for Thailand with unlimited data. However, unlimited does NOT mean unlimited on max speed. After 2 GB data usage per day the data speed is reduced to 512 Kbps. That is similar to an E-signal, barely good enough for WhatsApp and you will NOT be able to use social media anymore for 24 hours, until max data speed is restored.
Therefore Traveltomtom does NOT recommend the Nomad eSIMs for Thailand with 'unlimited' data! More about eSIMs with unlimited data later.
Specifications Nomad eSIMs for Thailand
The Nomad eSIMs for Thailand operate on the AIS 4G/LTE/5G network and only some plans are 5G ready. The Nomad eSIM plans have to installed within 60 days after ordering. The expiry of the plan will only start from the first moment the plan connects to a supported network. So even if you instal the plan in your home country, it only starts its validity from the moment you arrive in Thailand and use it for the first time.
For more info check the Nomad website.

Why ordering an eSIM for Thailand
As you have read I pretty much constantly use eSIMs for traveling around the world. Mind you that I am a full time nomadic travel blogger and that I am on the road constantly and use about 30 - 40 different sim cards every year.
eSIMs are the easiest way to stay connected when traveling to Thailand in 2024. You arrange everything online in just a couple minutes. No more visiting a sim card shop and swapping physical sim cards in your phone. Order online, scan the QR code, follow the steps and you are connected in less than 2 minutes.
The most important reason is because we would like to stay connected on our trip to Thailand. Our smartphones are pretty useless without a working data connection. Think about ordering a taxi through an app (Uber is Grab in Thailand), finding nearby friends, restaurants, bars. Get directions from Google Maps or simply stay in touch with family back home, check out social media apps on long bus rides or check your banking apps when paying contactless.
So many reasons to stay connected when traveling and it makes your trip to Thailand so much more convenient and fun!
When staying connected we also want to make sure to not waste money on high roaming charges. Many mobile internet operators are still charge $2 USD per MB, that means just opening the Instagram app will already cost you 25 MB * $2 = $50 USD! Not kidding…
eSIMs are also the easiest way to avoid high roaming charges!
Ever since 2012 I am continuously traveling the world as a full time travel blogger and nomad and I get to a different country pretty much every week. Staying connected is one of the first things I do when planning my next trip. In the past I used to buy a local prepaid sim card on arrival, but nowadays I mostly use eSIMs for staying connected when traveling abroad.
Some of my popular eSIM guides are the ones for: Asia, Europe, USA, China, Australia, Malaysia, Hong Kong, Singapore, Indonesia, United Kingdom, Germany, Italy, Spain, France, Greece, Canada, Turkey and international sim cards with data.
International Data Roaming plans
So what about overseas data roaming plans? Well, did you read at what speed you can use data roaming while traveling in Thailand? In most cases mobile internet operators limit the data speed for data roaming plans, which means you end up with 3G data speed, but there is 5G in Thailand everywhere!
Uncountable times travel friends have asked me: 'can I use your hotspot? My data roaming plan is so slow, it is barely working!'.
Trust me, get yourself an eSIM or an international prepaid sim card for traveling to Thailand. Spend a couple dollars extra and be connected all the time instead of begging for WiFi or a hotspot from friends.
Where to buy an eSIM for Thailand?
Online
You can only buy an eSIM for Thailand on the internet through an eSIM provider. There are multiple eSIM providers for Thailand nowadays. After comparing more than 7 eSIM providers Traveltomtom determined that these are the best eSIM providers for traveling to Thailand in 2024.
On arrival in Thailand
When you arrive in Thailand and looking to buy an eSIM for tourists then you will find out that all the Thailand mobile internet providers do NOT offer eSIMs for prepaid plans. All the tourist sim cards for Thailand come as physical prepaid sim cards. Tourist eSIMs are still not available as of November 2024.

How to activate an eSIM for Thailand
Don't worry about this, activating an eSIM is made as simple as possible by all the eSIM providers.
Once you choose your preferred eSIM plan for Thailand you click on 'order'. After the payment is processed you instantly receive a QR-code.
You will see a summary of your eSIM order including the QR code on your phone and you will also receive an email with the same QR code, directly after your payment has been processed.
The QR code contains all the information about your eSIM for Thailand and the only thing you have to do is scan the code with the phone where you want to instal your eSIM on.
Once you scan the code you will be guided through a couple simple steps and within less than 1 minute your eSIM is successfully installed. Make sure you are connected to the WiFi when installing your eSIM otherwise you will get an error.
Tip: if you order an eSIM with the same phone where you want to instal the eSIM on then ask a friend or someone nearby to take a photo of the QR code and then you scan the QR code from his/her phone and start the installation.
When to order an eSIM for Thailand?
You can order an eSIM for Thailand pretty much any time you want. Some eSIMs have to be installed within 1 month after ordering, some within 3 months after purchasing, so you have time.
More important therefore is when do you instal your Thailand eSIM. The validity of some eSIMs start straight after the installation, other eSIMs only start their plan when they connect the first time to a supported network.
Traveltomtom advices to instal your eSIM on the day of your departure to Thailand. Remember you must be connected to the internet to instal an eSIM.
Or if you want to maximise your Thailand eSIM plan then activate your the eSIM on arrival after you connect to the free WiFi of Bangkok Airport or Phuket Airport or use the WiFi in your hotel.
Things to know before ordering an eSIM for Thailand
Let me also give you some general tips for using eSIMs. These general tips do not only apply for Thailand eSIMs, but are things you need to know before buying an eSIM in general.
Make sure your phone is unlocked
To make sure you didn't miss this, let me say this again: eSIMs only work in UNLOCKED phones. If your phone is unlocked then you can use any eSIM for Thailand without any problems.
If your phone is locked then ask your mobile internet provider from your home country to unlock your phone before your trip to Thailand. It is likely that your mobile internet provider will charge you a fee for unlocking your smartphone.
If you are unable to unlock your phone you can look into getting a pocket WiFi for traveling to Thailand or bring a second unlocked phone with you on your Thailand trip and use it as a portable Wifi device.
Which smartphones support eSIMs?
Another very important condition you have to check before ordering an eSIM for Thailand is if your smartphone supports eSIMs. If you have any of the latest mobile phones then there is no need to worry, all new smartphones models support eSIMs.
The fastest way to find out if your phone is eSIM compatible is by asking Google the question: is my … phone eSIM compatible? Simple as that!
If your phone is NOT eSIM compatible then there is no solution. You simply can NOT use an eSIM for traveling to Thailand.
However, don't worry there is still the possibility to order a sim card for Thailand online. Check out my complete guide for buying a prepaid sim card in Thailand in 2024 for more info or check out my guide with everything you need to know before buying an international sim card for traveling abroad in 2024.
Can I trust the online eSIM providers?
All the eSIM providers for Thailand recommended in this guide are reputable eSIM providers reviewed and tested by Traveltomtom. All of them are licensed third party companies and resellers that partner or work directly with the mobile internet providers in Thailand.
Traveltomtom has used Airalo and SimOptions sim cards now for more than 5 years and never really faced a major issue.
Check out the pros and cons of SimOptions in our article: Honest Review of SimOptions.
The Traveltomtom Team has extensively tested and reviewed Nomad and they have proven to be a reliable eSIM provider. However, some mixed reviews have come back from the Traveltomtom Team about connectivity and activation.
Jetpac is a fairly new eSIM provider, but Traveltomtom only received positive feedback and excellent reviews about the eSIMs and services of Jetpac.
Sim Local has more than 100 sim card shops and kiosks in international airports around the world and has been selling sim cards for tourists for more than 5 years. Read Traveltomtom's honest review about Sim Local eSIM provider.
Since Traveltomtom is not a fan of eSIMs with unlimited data and an FUP I hardly use Holafly, but when I did I was not happy. So now I let the Traveltomtom Team randomly test Holafly and just like myself, mixed reviews have come back. Some positive, some negative.
On top of that there is now also Roamless, an eSIM provider with no data expiration. Truly a game changer!
Traveltomtom does NOT sell Thailand eSIMs, Traveltomtom only compares and recommends you to use eSIMs for traveling to Thailand.
All eSIM providers have their own Helpdesk which you can contact may you encounter any problems or in case you want to claim a refund.
Can I keep my phone number from home with an eSIM for Thailand?
Yes, you can and this is for many people a reason to order an eSIM to stay connected when traveling to Thailand. An eSIM can be used next to your physical or eSIM from your home country at the same time. You do not need a dual-sim phone for using an eSIM.
So you can have multiple eSIMs installed on your phone? Yes, no problem at all!
For example: you can turn off the mobile data from your sim card from home but still use it for texting and calling. The Thailand eSIM you can use just for data at the same time to ensure you are not wasting money on high roaming costs.
If your Thailand eSIM also allows you to make phone calls and you want to make a local call in Thailand, you simply switch between the sim cards and make a local phone call with your Thailand eSIM.
Can I make phone calls with an eSIM for Thailand?
This depends on the type of eSIM that you order. The SimOptions and Airalo eSIMs for Thailand support calls and sms, the Jetpac, Holafly and Nomad eSIMs for Thailand are data-only and calling and texting is not supported.
The DTAC Happy Tourist eSIM, the by Traveltomtom most recommended eSIM for Thailand, supports incoming and outgoing phone calls and sms. You can order the DTAC Happy Tourist eSIM via Airalo or SimOptions.
Does a Thailand eSIM come with a phone number?
This also depends on the type of eSIM that you buy. The eSIMs from Airalo and SimOptions that support calls and sms they come with a phone number. The eSIMs from Holafly, Jetpac and Nomad are data-only sim cards and do not support calling and texting and also do NOT come with a phone number.
The DTAC Happy Tourist sim card come with a Thai phone number that starts with +66.
All the specifications per Thailand eSIM are stated in my comparison of the best eSIMs for Thailand above.
Can I use 5G on a Thailand eSIM?
As of November 2024 pretty much all eSIMS for Thailand recommended in this guide are 5G ready.
Are there eSIMs for Thailand with unlimited data?
Yes, there are eSIMs for Thailand with unlimited data. However, this is mostly a marketing tool to make people buy an eSIM. Always make sure the unlimited data is on max data speed.
A very good example are the Nomad eSIM for Thailand with unlimited data. It seems like you get unlimited data but when you read the fine print it says that after 2 GB data per day you data speed is reduced. Which basically means data speed as if you are on an E-signal, barely enough for using WhatsApp or checking emails.
They limit (how ironic) the data speed for 24 hours down to 512 Kbps. Completely useless when you ask me.
Always ask yourself is unlimited truly unlimited. Is there a catch? If the unlimited data is not on max data speed, then there is a so called FUP. Which means that your data speed will be capped after you used an X amount of Gigabytes.
Holafly is an eSIM provider that sells eSIMs with unlimited data for Thailand and uses a so-called Fair Use Policy (FUP). Holafly does NOT specify what the FUP is. Which is very dissatisfying.
Traveltomtom does NOT recommend Thailand eSIMs with unlimited data plans with an FUP. On Holafly eSIMs I experienced a reduce in data speed after using more than 2 GB per day. After I contacted support they explained me that I had to wait for 24 hours until my data speed was restored to normal.
Those 24 hours were a nightmare as my data speed was barely enough to use WhatsApp. Social media was not even loading!
Especially on days that you have a long bus or train ride and you need a lot of data, you definitely don't want any data speed restrictions that day.
Again, Traveltomtom does NOT recommend eSIMs for Thailand with unlimited data. But if you think you will never use more than 2 GB per day, then Holafly might be your favorite eSIM.
However, if you don't use so much data per day then what's the point of an eSIM with unlimited data... is what you have to ask yourself.
Another reason why I advice you to take a close at my comparison of the best eSIMs for traveling to Thailand in 2024 and read all the specifications.
Or simply just go with my recommendation of the 5G ready DTAC eSIM from Airalo.
Best ways to stay connected when traveling to Thailand
Let me also introduce to you other ways to stay connected when traveling to Thailand. eSIMs are the easiest and fastest way to get data on your phone when traveling to Thailand, but there are more options.
There are 3 ways to stay connected when traveling to Thailand to avoid roaming charges:
- Local prepaid sim cards
- International prepaid sim cards
- eSIMs
Let me explain all the options and compare eSIMs, local prepaid sim cards and international prepaid sim cards for you to make you understand what is your preferred way to stay connected.
Local prepaid sim cards
If you use a lot of data a local prepaid sim card for Thailand is probably the cheapest way to stay connected depending on the length of your trip. However, local prepaid sim cards can only be purchased on arrival in Thailand.
There are endless opportunities to buy a sim card for Thailand at Bangkok Airport, check the link for more info and I will tell you if tourists are able to buy an eSIM for Thailand on arrival at Bangkok Airport or check out my vlog about my arrival and my experiences buying a sim card at Bangkok Airport in the link.
When in doubt about ordering an eSIM for Thailand and you want more info about Thailand prepaid sim cards then read my complete guide for buying a sim card for Thailand in 2024.
The advantage of local prepaid sim cards is that you buy them directly from the mobile internet provider. You get the cheapest prices, unlimited local calls & sms included, the biggest data packages and the fastest data speed. Local prepaid sim cards in Thailand all offer 5G, the max data speed on prepaid sim cards varies a lot per operator though.
International prepaid sim cards
For those who have smartphones that are not eSIM compatible or those who rather put a physical sim card in their phones there are also international prepaid sim cards with data for traveling to Thailand that you can order online.
You order an international prepaid sim card for Thailand on the internet. A pre-activated physical sim card will be delivered to your home address. You put this sim card in your phone during your flight and as soon as the plane touches the ground and the sim card connects to a supported network you are online. Plug and play.
Click here to order a physical international prepaid sim card for Thailand directly online via SimOptions.
The advantage of an international prepaid sim card is that it often includes calling and texting and eSIMs are mostly data-only sim cards.
eSIMs
In fact there are two eSIM options:
- eSIMs you buy on the internet through a third party
- eSIMs provided by the Thailand mobile internet providers
The big difference is that eSIMs provided by the local internet operators in Thailand: DTAC, AIS and True Move can only be purchased in Thailand at one of their phone stores.
However, none of the mobile internet providers in Thailand offer eSIMs for prepaid plans for tourists, only for postpaid and residents in Thailand are able to get a local eSIM plan.
Which makes it that if you want an eSIM for Thailand you will have to order one online from the above mentioned eSIM providers.
eSIMs vs. local prepaid sim cards
Getting an eSIM is the easiest way to stay connected when traveling to Thailand, no doubt! You arrange everything online within just a couple click. Right here, right now if you want and you are all set for your trip to Thailand. As soon as the plane lands, you are online.
But what is cheaper? An eSIM or a local prepaid sim card? When we compare Thailand eSIM prices with local prepaid sim cards for Thailand I come to the conclusion that buying a prepaid sim card on arrival in Thailand is a little cheaper.
With local Thailand prepaid sim cards you get more data for the same price, so for people that use a lot of GB's per day an eSIM will turn out to be a little more expensive.
The downside is that you can only buy a Thailand prepaid sim card after you arrive. So you won't be able to arrived prepared. On arrival in Thailand you will have to go to a sim card shop and buy a prepaid sim card for tourists.
After a long flight when you just want to go to your hotel that is often a big task and therefore a lot of travelers simply get an eSIM for Thailand. Faster, easier and less stress!
Data speed
Another difference between a local prepaid sim card and an eSIM is that eSIMs are often through a third party, a so called MVNO (Mobile Virtual Network Operator). These MVNO's operate the network of one of the main mobile internet operators and basically buy bandwidth on the mobile data network from one of the main mobile internet providers.
This may sound a little bit too technical, but what it means is that eSIMs through an MVNO are the last ones in line. Especially during peak times, the performance of an eSIMs is less compared to local prepaid sim cards directly bought from a mobile internet operator.
Bottomline: the data speed of eSIMs can be less compared to a local prepaid sim card.
In case the eSIM is provided directly by the main mobile network operator like in Thailand for example from DTAC then the above does NOT apply. However, if you for example order a SimOptions Thailand eSIM then you are last in line at peak times.
I am sure some of the above tips for finding an eSIM for your trip to Thailand were helpful. I hope that after reading through my comparison of the best eSIMs for Thailand it was easier to make a decision and order your eSIM right away.
