How does Simbye eSIM work for Thailand?
Order before you fly
Pick the length, pay, and the eSIM arrives by email. Set it up calmly at home on Wi-Fi: tap the link or scan the QR code and you are done. The line then sits dormant on your phone and the clock has not started yet.
Switch it on in Thailand
After landing at Bangkok Suvarnabhumi or Don Mueang, in Phuket, Chiang Mai, Krabi, Koh Samui, U-Tapao near Pattaya or Hat Yai, simply turn off airplane mode. Your phone registers with TrueMove H or DTAC by itself. Just check that data roaming is switched on for the eSIM.
Go online
Turn on data roaming for the eSIM and you are connected. The line also carries a Thai +66 number that can receive calls and texts. Outgoing calls and texts are barred by the operator, so the number is for receiving only. The clock starts with your first connection in Thailand, not at purchase.
Check Device Compatibility
Make sure your device supports eSIM before purchasing
Which networks will you be on in Thailand?
Your Thailand eSIM runs on TrueMove H and DTAC, both part of True Corporation since the merger.
The Simbye eSIM uses 2 networks in Thailand: TrueMove H · DTAC.
| Networks | Download | Upload | Latency |
|---|---|---|---|
| TrueMove H | 77Mbit/s | 24Mbit/s | 30ms |
| DTAC | 51Mbit/s | 15Mbit/s | 37ms |
Source: nPerf averages, 01.01.2025 – 31.12.2025.
You do not pick a network. The moment you land in Thailand and switch off airplane mode, your phone finds the strongest signal from TrueMove H or DTAC on its own, and it switches between them as you travel. There is nothing to enter by hand. Two things matter: data roaming has to be on for the eSIM, and the eSIM has to be selected as your mobile data line, so your phone stops using your card from home.
You are connected in the arrivals halls of Suvarnabhumi and Don Mueang already, and at Phuket airport too. In Bangkok, Chiang Mai, Phuket, Pattaya, Hua Hin, Krabi and Hat Yai you get 4G almost everywhere and 5G across large parts of the cities. On the bigger islands – Koh Samui, Koh Phangan, Koh Chang, Koh Lanta – coverage is solid in the towns, on the beaches and at the piers, but it thins out inland and in the hills. On very small islands such as Koh Tao or Koh Lipe, in Khao Sok National Park and on the mountain roads around Pai and Mae Hong Son you should expect dead spots, and on the ferries between the mainland and the islands the signal drops out for stretches. Download your maps, tickets and the address of your accommodation before you set off.
eSIM or a local SIM card in Thailand?
Thailand is the clearest case: since August 2025 a shop card means your passport plus a live photo in the shop, while the eSIM arrives by email with its own +66 number for incoming calls and texts, and works the minute you land at Suvarnabhumi.
| Feature | Local SIM card | |
|---|---|---|
| Passport and face scan | Not needed, the eSIM arrives ready by email | Required since August 2025: show your passport and have a live photo taken in the shop |
| When you are online | Right after landing, still in the arrivals hall at Suvarnabhumi | Only after queueing at the counter, often 20 to 40 minutes |
| Paying | In advance from home in your own currency | On the spot in baht, cash or card at the counter |
| When you can book it | As soon as your flight is booked, set up at home | Only after you arrive, depending on opening hours and the queue |
| Thai phone number | +66, receives calls and texts | +66, calls and texts both ways |
| Your number from home | Stays active, people can still reach you | Only if your phone handles two lines at once |
| When the clock starts | With your first connection in Thailand | On the day you buy it in the shop |
| Maximum length | 7 to 30 days, then you simply book again | Tourist SIMs are capped at 60 days, then you register again with your passport |
For most travelers the eSIM is the simpler choice: set up before departure, no queuing on arrival.

Frequently Asked Questions about Thailand eSIM with Calls & Phone Number
Data, calls, real phone numbers, top-ups and setup — everything you need to know before you buy a Simbye eSIM.
Yes, the eSIM works across all of Thailand. It connects to TrueMove H and DTAC, which now belong together under True Corporation. In Bangkok, Chiang Mai, Phuket, Krabi, Pattaya, Hua Hin and on the big islands you have steady reception. In national parks, in the northern mountains and on very small islands there are dead spots, but that is equally true of any SIM you buy at the airport.
Yes. This eSIM comes with a real phone number using the +66 country code, and it can receive calls and texts. Outgoing calls and texts are barred by the operator, so the number is for receiving only.
You can buy a Thailand eSIM right here on this page, and it reaches you by email within minutes. An eSIM for Thailand is a digital SIM card built into your phone. An eSIM for Thailand is delivered digitally: nothing is shipped, there is no plastic card and no contract. You set it up at home with the QR code from the email and never queue for it in Thailand.
Yes, there is a Thailand eSIM for 30 days - the longest plan runs a full 30 days, the shortest one week. The clock starts with your first connection in Thailand, not on the day you order, so ordering early does not cost you any days.
No, you don't have to register with your passport, or queue anywhere. Anyone buying a Thai prepaid card on the spot has, since August 2025, had to show their passport and have a live photo taken of their face. Your eSIM arrives ready by email.
Both give you a +66 number. The local card only comes after queueing at the counter, with a passport check and a face scan, and tourist SIMs are capped at 60 days. The eSIM is already on your phone before you fly.
Yes, the Thailand Digital Arrival Card is required, but unrelated to the eSIM. Since 1 May 2025 every foreign visitor has to complete the TDAC online before entry, at the earliest 72 hours before arrival, at tdac.immigration.go.th. Do it at home on Wi-Fi, because without the confirmation border control can turn you away.
A Thailand eSIM starts at 19,95€, and the price depends on the number of days and the data you need - the price table above on this page lists each Thailand plan with its validity. A one-week beach trip needs less than a month of island hopping with maps, ride-hailing apps and video calls home.
How much data matters less for Thailand, since this plan is unlimited - it's about how hard you'll use it. Maps and messaging around Bangkok cost a few hundred MB a day. Island hopping with daily photo uploads sits near 1 GB. Streaming on night buses or tethering a laptop from Chiang Mai runs several GB a day, and all of it is covered.
