Why Travellers Choose GleeSim for Thailand
Since 2025, a local Thai SIM needs your passport and a live face scan at an operator counter. GleeSim skips the counter: you install the eSIM at home and it works when you land, from $1.80.
No Counter, No Face Scan
Local SIMs at Suvarnabhumi and Don Mueang now need passport checks and a face scan, and the queues get long after big flights land. Your eSIM is ready before you board.
Built for Island Hopping
A Thailand eSIM for island hopping keeps maps, ferry tickets and hotel chats working from Phuket to Koh Phi Phi, Koh Samui and Koh Phangan, with no new SIM on each island.
Thailand eSIM: Christmas, New Year Ready
Need a Thailand eSIM? Christmas, New Year and the Full Moon Party are the busiest weeks of the year. Order now, install at home, and your data works the moment you land.
Thailand Plus Four Countries
The Southeast Asia plans also cover Malaysia, Singapore, Indonesia and the Philippines, so a Bangkok and Bali or Phuket and Kuala Lumpur trip needs one QR code.
Keep Your Own Number
GleeSim runs as a second data line. Your home SIM stays in the phone, so your WhatsApp number and bank codes keep working.
Top Up on WhatsApp
Running low on Koh Samui? Send one message and we add data to the same eSIM. No 7-Eleven top-up card and no new SIM.
Choose Your Thailand Data Plan
Pick Thailand Only for a single-country trip, or Southeast Asia to add Malaysia, Singapore, Indonesia and the Philippines. Plans start at $1.80 for the five-country Southeast Asia plan, or $6.26 for Thailand only. Use code GLEE10 when you order on WhatsApp for an extra 10% off.

Frequently Asked Questions
Answers to the questions travellers ask us most before a Thailand trip.
What is the best eSIM for Thailand Christmas New Year 2026?
The best eSIM for Thailand at Christmas and New Year 2026 is one you install before you fly, so you skip the airport SIM queues on the busiest travel days of the year. For a two week holiday, the Thailand 5GB, 30 Days plan at $6.26 covers most people. If you are island hopping or posting lots of video, choose the Thailand 10GB, 30 Days plan.
Thailand eSIM vs airport SIM Bangkok: which is better?
The AIS and True tourist SIMs at Suvarnabhumi are good value, from around 299 baht, and include a Thai number. Since 2025 you also need a passport check and a live face scan at the counter, and queues can be long when several flights land together. A Thailand eSIM is installed at home, so you are online as soon as you land and your own SIM stays in the phone. If you want a Thai number and don't mind the queue, the airport SIM is fine. If you want to walk straight out to your taxi, choose the eSIM.
Does Thailand require a registered SIM for tourists?
Yes, for local Thai SIM cards. Tourists buying an AIS or True SIM must show a passport and, since August 2025, complete a face scan at the counter. A GleeSim eSIM works on roaming and is set up before you travel, so there is no counter visit.
Is there a Koh Samui eSIM?
Yes. Every plan on this page works on Koh Samui, where Chaweng, Lamai and Bophut have excellent 4G and 5G. A Koh Samui eSIM also keeps working on day trips to Ang Thong and on the ferry to Koh Phangan near the piers.
What is the data coverage on Koh Phangan?
Data coverage on Koh Phangan is good in Haad Rin, Thong Sala and the main beaches, with 4G on AIS and True. On Full Moon Party nights thousands of phones share the same masts around Haad Rin, so speeds can drop. Remote beaches on the north and east coasts have weaker signal.
Is there an eSIM for a Full Moon Party New Year?
Yes. For an eSIM for a Full Moon Party New Year trip, install it before you fly and send your meeting point to friends before the party starts, when the network is quieter. The Thailand 10GB, 30 Days plan covers a Koh Phangan New Year plus the rest of your trip.
Which Thailand eSIM plan should I choose?
For a week or two, the Thailand 5GB, 30 Days plan at $6.26 is the best value. For island hopping, Grab rides and lots of photos, choose 10GB. For a month of heavy use or remote work, the Thailand 30GB plans cover 30 or 90 days. If you are also visiting Malaysia, Singapore, Indonesia or the Philippines, pick a Southeast Asia plan.
Does the eSIM work at Bangkok and Phuket airports?
Yes. Suvarnabhumi, Don Mueang and Phuket airports all have strong 4G and 5G. If you installed your eSIM at home, it connects as soon as you turn on Data Roaming after landing.
Can I use Grab and Bolt with the eSIM?
Yes. Grab and Bolt work on mobile data, so you can book and track rides in Bangkok, Phuket, Chiang Mai and on Koh Samui. Some Thai payment apps need a Thai number, so pay by card or cash where they do.
Do WhatsApp calls work in Thailand?
Yes. WhatsApp messages and voice and video calls work normally in Thailand on mobile data. Call quality depends on your signal, so calls are clearest in towns and resort areas.
Does the Thailand eSIM work in Malaysia or Singapore?
The Southeast Asia plans do. They cover Thailand, Malaysia, Singapore, Indonesia and the Philippines on one QR code. The Thailand-only plans work in Thailand only.
Is my phone compatible with the Thailand eSIM?
Any eSIM-capable phone that is not locked to one network works. That includes iPhone XS and newer, Samsung Galaxy S20 and newer, Google Pixel 3 and newer, and most recent flagship Android phones. Look for an Add eSIM option in your mobile data settings.
Does this plan include a Thai phone number?
No. The GleeSim Thailand eSIM is data only and does not include a +66 number for normal calls or SMS. Your home number stays active on your main SIM, and you can call hotels and tour operators over WhatsApp.
What happens if I run out of data in Thailand?
Send us a WhatsApp message and we add more data to the same eSIM within minutes. You don't need a new QR code or a top-up card from 7-Eleven.
Can I buy a Phuket eSIM from UK before I fly?
Yes. A Phuket eSIM from UK works like an order from anywhere else. Message us on WhatsApp, pick a plan, and your QR code arrives in the chat in about 60 seconds. Install it at home on WiFi, then switch it on when you land at Phuket Airport. The Thailand 5GB, 30 Days plan at $6.26 covers most two week holidays, and the same plan works in Bangkok, Koh Samui and Krabi.
