Thailand eSIM for Travellers
Travel eSIM data in 210+ countries
Heading to Bangkok, Phuket, Chiang Mai or the islands? Install a travel eSIM before you go and land with mobile data ready for maps, ride-hailing, translations and staying in touch.
Why use an eSIM here
- Data from the moment you land at Suvarnabhumi, Don Mueang or Phuket.
- No need to buy a tourist SIM at the airport.
- Perfect for island hopping, where Wi-Fi can be slow.
- Keep your home number active for calls and bank texts.
How to get connected in 3 steps
- Choose your plan on our eSIM page and enter code CONNECT at checkout.
- Install the eSIM before you travel by scanning the QR code you receive by email (most recent iPhones, Samsung Galaxy and Google Pixel phones support eSIM).
- Turn on the eSIM line and data roaming for it when you land – your normal SIM can stay in the phone for calls and texts.
Travel tips
- Download offline maps and a translation app before you fly.
- Ride-hailing apps work best with mobile data.
- Choose a bigger data plan if you share hotspot data or upload many videos.
Questions travellers ask
How much data do I need for a week in Thailand?
For maps, messages and social media, many travellers use around 1 GB every two to three days. If you stream video or use hotspot, choose a larger plan.
Does my phone support eSIM?
Most recent iPhones (XS and newer), Samsung Galaxy S and Z models and Google Pixel phones support eSIM. Your phone must also be unlocked. You can check under Settings: if you see “Add eSIM” or “Add mobile plan”, it is supported.
Can I keep my WhatsApp and my normal number?
Yes. The eSIM only gives you data. Your normal SIM and number stay in the phone, and WhatsApp keeps working with your usual number.
