eSIM for Thailand
Thailand has three national mobile networks, and a ScarabPay eSIM can use all of them: AIS, TrueMove H and DTAC, each with 5G in the main cities. That matters on island-hopping trips, where one network may be stronger than another. Install by QR code at home and land in Bangkok already online.

Mobile internet in Thailand: what travellers should know
Bangkok, Chiang Mai, Pattaya and the resort areas of Phuket and Koh Samui have dense 4G and 5G coverage from AIS, TrueMove H and DTAC. Beyond the cities, signal is generally good along main roads and in tourist towns, but it can weaken in the northern mountains around Pai and Mae Hong Son, inside national parks such as Khao Sok, and on smaller, less developed islands in the Andaman Sea and the Gulf.
Thailand requires passport registration for local SIM cards, and the tourist SIM counters at Suvarnabhumi and Don Mueang can have long queues after busy arrivals. Free Wi-Fi is available in most hotels, guesthouses, cafes and malls, but speeds vary. Grab and Bolt are widely used for rides, Google Maps for getting around, and LINE is the messaging app many Thai businesses and hotels use to talk to guests.
Add the eSIM on Wi-Fi before you leave and switch it on after landing, with data roaming enabled for the eSIM line alone. Your home SIM can stay active for bank codes with its data off. A short Bangkok stopover needs little data; a two-week loop through Chiang Mai and the islands uses far more, especially if you upload photos or share a hotspot. Top up online if needed.
Quick tips for Thailand
- Install LINE before you travel; many guesthouses, tour operators and dive shops confirm bookings through it.
- Save ferry tickets and hotel addresses offline before crossing to Koh Phi Phi, Koh Lanta or Koh Tao.
- Use Grab or Bolt for rides in Bangkok so the price and route are fixed before you set off.
- On the winding road to Pai, load your route in advance; mountain stretches may lose signal for a while.
- Heading to Cambodia, Laos or Malaysia afterwards? A regional Asia plan suits multi-country trips better than this single-country plan.
Frequently asked questions
Does the eSIM work on Thai islands like Koh Tao and Koh Phangan?
On the main islands, yes: the beaches, villages and piers on Koh Samui, Koh Phangan, Koh Tao and Phuket are covered by AIS, TrueMove H or DTAC. On remote bays, small outlying islands and during ferry crossings the signal can drop. Download maps and boat schedules before you go.
Do I need to show my passport to use this eSIM in Thailand?
Local Thai SIM cards bought at the airport or in shops must be registered with a passport. With this eSIM you buy online and install it by QR code before the trip, so you do not need to visit a SIM counter on arrival. Keep your passport for check-in and other official purposes.
Which network will my phone use in Thailand?
The plan lists AIS, TrueMove H and DTAC, and your phone connects to one of these depending on availability where you are. If the signal is weak, you can usually choose another listed network manually in your phone's mobile settings. All three offer 5G in the main cities.
How do I activate my Thailand eSIM?
After you pay, open the QR code in your ScarabPay account and scan it in your phone settings. The Thailand data plan installs in a minute or two, and you can turn it on when you arrive.
When should I install the eSIM?
You can install it before your trip and switch it on once you reach Thailand. The validity period starts when the plan first connects to a network, not when you install it.
Can I keep my own number in Thailand?
Yes. The Thailand eSIM handles mobile data while your regular SIM stays active for your usual number, so you can still receive calls and texts.
What if I run out of data in Thailand?
Simply buy another Thailand plan from your ScarabPay account. You can top up as many times as you need, paying from your wallet or with crypto each time.
Do I need a ScarabPay account?
Yes. You buy and manage your Thailand eSIM from your ScarabPay account, which also gives you one place for your wallet, cards and payments. Creating an account takes only a few minutes.
Ready for your next trip?
Get online in Thailand the moment you arrive. Choose a data plan, pay from your ScarabPay wallet or with crypto, and receive your QR code instantly, no physical SIM and no roaming bills.
