eSIM Thailand – Fast, Easy, 5G Data for Travellers
Dreaming of street food in Bangkok, sunsets in Phuket and cafés in Chiang Mai but dreading airport SIM queues and confusing roaming bills? An eSIM for Thailand lets you land, switch on data, and start exploring in minutes.
With the Ezy eSIM Thailand plan, you get high-speed 4G/5G data on Thailand’s leading networks AIS 5G and TrueMove H 5G, plus instant digital delivery and flexible plan options from short stay trips through to long escapes.
Why use an eSIM in Thailand?
Travellers choose an eSIM over a traditional plastic SIM because it’s:
-
100% digital – buy online, receive a QR code instantly, no store visits.
-
Ready the moment you land – activate over Wi-Fi before or on arrival and skip airport SIM queues.
-
Perfect for Google Maps & apps – reliable data for Grab, hotel bookings, messaging apps and travel guides.
-
No contract or ID hassles – Thailand eSIM from Ezy eSIM doesn’t require local ID verification.
-
Keep your physical SIM – stay reachable on your home number while using cheap local data.
If you’re hopping to multiple countries, you can also look at multi-country options like the Asia eSIM or Global eSIM alongside your Thailand plan.
Coverage & Networks in Thailand
Your Thailand eSIM connects to AIS 5G and TrueMove H 5G, two of the biggest network operators in the country.
You’ll enjoy strong coverage in:
-
Bangkok – ideal for BTS/MRT navigation, ride-hailing and remote work in cafés.
-
Chiang Mai & the north – stay online as you temple-hop or head into the hills.
-
Phuket, Krabi & island getaways – data for beach towns, ferries and island-hopping routes.
-
Pattaya & Gulf coast – coverage across highways and resort areas.
-
Major highways and tourist hotspots across the country.
Coverage is excellent in cities, towns and key tourist regions. For very remote areas or national parks, it’s smart to pre-download offline maps as speeds can vary, just like with any provider.
Thailand eSIM plan options
The Ezy eSIM Thailand product offers a range of data-only plans, so you can match the bundle to your trip:
-
From 1GB for 7 days – perfect for a short stopover.
-
Mid-range options like 3–10GB with 15–30 day validity for standard holidays.
-
Larger 20GB+ bundles for longer trips or heavier data users.
-
A long-stay option with up to 50GB available for 180 days – ideal for digital nomads and extended stays.
Pricing starts from around USD $2 for the smallest plan, making it far cheaper than typical international roaming rates.
All Thailand eSIM plans are:
-
Data-only (no traditional voice or SMS)
-
Full-speed 4G/5G – no artificial slow-downs while you have data remaining
-
Hotspot/tethering friendly – share your connection with laptops, tablets or friends.

How activation works (step-by-step)
Setting up your eSIM for Thailand usually takes just a few minutes. Here’s the simple flow based on Ezy eSIM’s activation process:
1. Check your phone supports eSIM
Most unlocked smartphones from around 2018 onwards support eSIM.
-
On your phone, dial *#06#.
-
Look for an EID number in the results – that’s your eSIM ID.
-
Make sure your device is carrier-unlocked (not restricted to one operator at home).
2. Buy your Thailand eSIM online
-
Visit the Thailand eSIM product page.
-
Choose the data amount and validity that suits your trip.
-
Complete checkout.
-
You’ll receive an instant digital QR code and setup instructions by email/onscreen.
3. Install the eSIM profile
You can install your eSIM:
-
Before you fly, while connected to Wi-Fi at home, or
-
On arrival in Thailand, using airport Wi-Fi or hotel Wi-Fi.
On most phones (wording will vary slightly by OS):
-
Go to Settings → Mobile / Cellular → Add eSIM.
-
Scan the QR code provided by Ezy eSIM (or enter the details manually if needed).
-
Label the new eSIM (e.g. “Thailand Data”).
-
Set your home SIM for calls/SMS and Thailand eSIM for mobile data.
4. Activate on arrival
The Thailand eSIM has a generous 180-day activation window – you can install it any time, but the validity only starts when your phone first connects to a Thai network (AIS or TrueMove H).
On arrival in Thailand:
-
Turn off Airplane Mode.
-
In settings, switch mobile data to the Thailand eSIM.
-
Make sure Data Roaming is ON for the eSIM profile.
-
Your device should automatically latch onto AIS 5G or TrueMove H 5G and go online within seconds.
5. Use, monitor & top up
-
Track your data usage in your phone’s normal data settings.
-
When your balance is low, you’ll receive automated SMS alerts, and you can top up online through Ezy eSIM.
-
Tether to laptops, tablets or travel companions as needed – hotspot is supported.
If you factory reset your device or want to move the eSIM, Ezy eSIM support can guide you through the process to keep your connection smooth.
Thailand eSIM vs roaming & local SIM
Trying to decide between an eSIM, your home carrier’s roaming pack or buying a SIM in Thailand? Here’s a quick comparison:
eSIM for Thailand (Ezy eSIM)
-
Cost: Low upfront cost; plans from just a few dollars.
-
Setup: Digital – no store visits or ID needed.
-
Speed: Fast 4G/5G on AIS and TrueMove H.
-
Flexibility: Keep your home number active on your physical SIM.

Traditional international roaming
-

-
Setup: Easy (you just turn it on), but you may need to pre-enable it and watch for bill shock.
-

Local physical SIM in Thailand
-
Cost: Can be cheap, but often requires queues at the airport or malls.
-
Setup: Requires passport ID, paperwork, and swapping SIM cards.

Holiday makers – 7–15 day bundles are ideal for a standard trip.

FAQ – eSIM for Thailand
Does this eSIM cover the whole of Thailand?
The Thailand eSIM uses AIS 5G and TrueMove H 5G, giving strong coverage in big cities, tourist hotspots, highways and many islands. In very remote or rural areas, coverage can be thinner, so it’s smart to download offline maps as a backup.
Is hotspot/tethering allowed?
Yes. Ezy eSIM specifically supports hotspot/tethering, so you can connect laptops, tablets and friends to your phone’s data without extra charges from Ezy eSIM.
How do I know if my device is compatible?
-
Dial *#06# on your phone.
-
If you see an EID number, your device supports eSIM.
-
Your phone should also be unlocked (not locked to one carrier).
Most recent iPhone, Google Pixel, Samsung Galaxy and other flagship devices from 2018 onward are compatible.
When does the validity period start?
There’s a large 180-day activation window. You can buy and install the eSIM at any time, but the validity only starts when your phone first connects to a supported Thai network (AIS or TrueMove H).
Can I use it for calls and SMS?
The Thailand eSIM is data-only. It doesn’t include traditional voice minutes or SMS. Instead, you can use apps like WhatsApp, Telegram, Messenger, Viber or FaceTime Audio for calls and messages. Your physical SIM can still handle regular calls and SMS from your home carrier if needed.
What if I reset my phone or want to move the eSIM?
Because eSIMs are digital profiles, moving or reinstalling them after a reset can require some extra steps. Ezy eSIM’s support team can help you reinstall on the same device after a reset or assist with moving to a new phone, depending on the plan’s rules and device capabilities.
Can I top up if I run out of data?
Yes. Ezy eSIM allows online top-ups, and you’ll receive automated SMS alerts when your data is running low so you can recharge before you’re cut off.
