The (almost) 5-star eSIM
The eSIM was very easy to install and, once I reached my destination, I had a connection from the very first moment without having to worry about roaming.
Activation was quick and simple, and I had a connection the whole time with no hassle. Coverage and speed were very good.
I went on a trip around Latin America and had coverage everywhere, at a very good price. Highly recommended 💪🏼

More about the Thailand eSIM
eSIM for Thailand: internet without roaming
Travel through Thailand with mobile data from the minute you land and forget about hunting for a store to buy a SIM. Our eSIM for Thailand connects to the country's main networks, AIS, TrueMove H and dtac, so you get 4G and 5G coverage both in the city and in tourist areas. Book hotels, order a Grab, use Google Maps around Bangkok's temples or send photos of Krabi's beaches without relying on your accommodation's Wi-Fi. Discover this and other available destinations in no time.
Roaming in Thailand: why an eSIM makes sense for you
Thailand is not part of the European Union, so "roam like at home" doesn't apply: your carrier will charge you non-EU rates, which usually run around 10 to 15 € per day or very limited data blocks that run out quickly. On a two-week trip that easily adds up to over 100 € just for connectivity. With an eSIM you buy your data upfront at a fixed price, with no surprises on your bill when you get back and no worries about overusing.
How much does an eSIM for Thailand cost?
You choose based on the days and your usage. For a short trip with maps and messaging, 1 GB for a few days does the job. For two or three weeks moving between Bangkok, Chiang Mai and the islands, with social media and some video, budget between 5 and 10 GB. If you're going to share the connection or work remotely, go for larger plans or generous data packages. It's always cheaper than roaming and cheaper than buying a local card at the airport.
eSIM vs physical SIM in Thailand
The physical SIM card from AIS or True that they sell at Suvarnabhumi airport works, but it means queuing, showing your passport and physically swapping your chip, with the risk of losing your home one. The eSIM is digital: you install it before you leave by scanning a QR code and you arrive with data already active. Plus you keep your regular number working to receive bank SMS or calls while you use your Thai data.
Does the eSIM work in Bangkok, Phuket and Chiang Mai?
Yes. Coverage from AIS, TrueMove H and dtac is solid in Bangkok, Chiang Mai, Phuket, Pattaya, Krabi and Koh Samui, with good speeds in urban and tourist areas. On small islands or jungle routes the signal may drop, as with any local carrier, but for 99% of your trip you'll have plenty of data for browsing, maps and internet calls.
How do you activate the Thailand eSIM?
After purchase you receive a QR code by email. You scan it from your phone's settings, the profile installs, and you activate the data when you arrive in Thailand. Everything in a few minutes and no tools needed. If it's your first eSIM, follow our eSIM guide step by step and check beforehand that your phone is compatible. You'll arrive connected and ready to enjoy your trip.
