Why travelers choose it
A Thai line, set up before you fly
Local True–DTAC network
A Thai network eSIM, not a roaming SIM from abroad. Data roaming can stay off on this line.
Online before the SIM queue
Install at home on Wi-Fi. At Suvarnabhumi, Don Mueang, or Phuket you switch it on and walk to the taxi rank.
Keep your own number
The eSIM sits next to your home SIM. WhatsApp and bank texts keep working on your usual number.
Secure checkout by Whop
Card payment runs on Whop inside this page. Your QR code arrives by email and stays on your order page.
✓ Good fit if you want
Data for Grab, maps, and hotel Wi-Fi codes in Bangkok, Chiang Mai, Phuket, or the islands, without queueing at a SIM counter in arrivals.
— Not the right plan if
You are staying longer than 30 days, or you need a number registered in your own name for Thai banking or long-term paperwork.

Where you’ll use it
From Bangkok to the islands
Skytrain, river boats, and a lot of map checking.
Bangkok
In Bangkok you use mobile data mostly for maps between BTS and MRT stations, Grab or Bolt rides, and messages to hotels and restaurants. A local True–DTAC eSIM covers the city, and the 7-day 15 GB plan fits a typical city stopover.
Read the guide →The old city, Nimman cafés, and roads into the hills.Chiang Mai
A Thailand eSIM works in Chiang Mai the same way it does in Bangkok. Chiang Mai Airport (CNX) is only a short drive from the old city, so turn the line on as you land and book Grab or Bolt from the terminal. On mountain roads to Doi Inthanon or Pai, expect signal to come and go.
Read the guide →Patong, Kata, Karon, and boats to Phi Phi and Phang Nga Bay.Phuket and the islands
In Phuket, mobile data matters most between the beaches and on tour days: booking Grab from Kata to Patong, checking pier times for Phi Phi, or finding your tour pickup. A local True–DTAC eSIM covers the island’s towns and beaches, and signal drops only far out at sea.
Read the guide →Gulf islands reached by plane or ferry.Koh Samui
The same Thailand eSIM works on Koh Samui, Koh Phangan, and Koh Tao, so you do not need a new SIM for the Gulf islands. Install it before you leave home, and buy enough days to cover the whole trip, including the flight or ferry from Bangkok.

eSIM vs airport SIM vs roaming
| eSIM for Thailand | Airport SIM | Home roaming | |
|---|---|---|---|
| Where you buy | On this site, before the flight | SIM counter after baggage claim | Your home carrier’s daily pass |
| Bangkok arrival | QR already installed | Queue at Suvarnabhumi or Don Mueang | Works if the pass is on, often pricey |
| Hotspot | Depends on the package you select | Ask the counter | Often blocked or capped |
| Passport | Not at checkout. Calls plans: store check before outgoing calls/SMS | Shown at the counter | Not required |
Is your phone eSIM-ready?
iPhone XS, XR, and newer, Samsung Galaxy S20 and newer, and Google Pixel 3 and newer support eSIM. The phone must be carrier-unlocked. Dial *#06#: if you see an EID, the phone supports eSIM.
Do the plans include calls?+
The Unlimited + calls plans include calls and SMS. Outgoing calls and SMS work after a passport check at a True or dtac store in Thailand; data and incoming calls work right away. The 15 GB and 50 GB plans are data only, so keep your home SIM on for calls and SMS.
Do I need to turn on data roaming?+
No. These eSIMs run on the local True–DTAC network in Thailand, so data roaming is not needed for this line.
Where should I install it?+
On Wi-Fi at home or in the airport lounge, before you need maps outside Suvarnabhumi or Don Mueang.
Does it work on the islands?+
Use it in Bangkok, Chiang Mai, Phuket, and Samui the same way. Signal on remote beaches and boats depends on the local network.
Can I buy two plans in one order?+
Yes. One checkout, one email, and a QR for each eSIM.
Do I upload a passport?+
Not at checkout. The data plans never need one. On the Unlimited + calls plans, Thailand’s NBTC rules require a passport check at an official True or dtac store in Thailand before outgoing calls and SMS work. Data and incoming calls work without it.
Do I need to show my passport for the Unlimited + calls plans?+
Only if you want outgoing calls and SMS. Data and incoming calls work right after activation. Under Thailand’s NBTC rules, from May 20, 2026 outgoing calls and SMS on the 8, 15, and 30-day Unlimited + calls plans need a quick passport check at an official True or dtac store in Thailand.
Why can’t I make calls or send SMS on my Unlimited + calls eSIM?+
Outgoing calls and SMS turn on after a quick passport check at a True or dtac store in Thailand, as required by the NBTC since May 20, 2026. Your internet and incoming calls already work, and WhatsApp or LINE calls work over data without the check.
How much data do I need for a week in Thailand?+
Most travelers use 1 to 2 GB a day for maps, Grab, chat, and social media, so 15 GB covers a typical week. Heavy video or laptop use suits an Unlimited + Calls plan.
Does my phone support eSIM?+
Dial *#06#. If you see an EID number, the phone supports eSIM. It must also be unlocked from your home carrier.
Do I still need the Thailand Digital Arrival Card?+
Yes. The eSIM does not replace it. Submit the free TDAC at tdac.immigration.go.th within the three days before you arrive.
What if the QR never arrives?+
The order page keeps it. If the eSIM cannot be issued, our team is alerted and the order is refunded.
