Thailand eSIM — common questions

Everything travelers ask before their trip to Thailand.

How much does a Thailand eSIM cost?
DataSIM Thailand plans are all valid for 30 days: 3 GB for $3.60, 5 GB for $5.40, 10 GB for $9.40, 20 GB for $16.40, and 50 GB for $61.20. No contracts or hidden fees, and you can top up anytime in the app.
Does the eSIM work on the Thai islands?
Yes — one eSIM covers all of Thailand, including Phuket, Koh Samui, Koh Phangan, Koh Tao, Koh Lipe, Krabi, and the Phi Phi Islands. You won't need a separate plan when island-hopping.
Will the eSIM work on ferries between Thai islands?
Coverage works on ferries when you're within range of the coast or near an island — strong near departure and arrival ports, intermittent during longer open-sea crossings. This is a limit of the cellular network itself, not the eSIM, and applies to every provider.
Will WhatsApp, LINE, and Grab work in Thailand?
Yes — WhatsApp, LINE (the dominant messaging app in Thailand), Grab, Google Maps, Instagram, and your usual apps all work normally on your DataSIM eSIM in Thailand, and you keep your existing number.
Will it work if I cross into Cambodia, Laos, or Malaysia?
The Thailand plan covers only Thailand. If your trip includes a temple-run to Angkor Wat, Luang Prabang, or Penang, you'll need a separate plan for each country, or check the multi-country Southeast Asia option in the DataSIM app.
Do I need to register my passport for a Thai SIM like with a local one?
No. Local Thai SIMs require passport registration under NBTC rules. A DataSIM travel eSIM requires no passport registration, no shop visit at Suvarnabhumi or Don Mueang airport, and no kiosk queues. Buy it in the app before you fly and install in minutes.
Can I use my eSIM as a hotspot in Thailand?
Yes, hotspot and tethering are supported on all DataSIM plans, so you can share your connection with a laptop or travel companions.
Does my phone support eSIM?
Most phones from 2019 onward do — including iPhone XS and later, Google Pixel 3 and later, and recent Samsung Galaxy models. Your phone must be carrier-unlocked.
When should I install my Thailand eSIM?
Install it before you travel, while you're on Wi-Fi. The plan only starts when the eSIM connects to a network in Thailand, so installing early costs nothing.
What happens when my data runs out?
Top up instantly in the DataSIM app — no need to install a new eSIM.
