More about the Thailand eSIM
eSIM for Thailand: internet without roaming
Travel through Thailand with mobile data from the moment you land and forget about looking 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 have 4G and 5G coverage in both cities and tourist areas. Book hotels, order a Grab, use Google Maps through the temples of Bangkok, or send photos of Krabi's beaches without relying on the accommodation's Wi-Fi. Discover this and other available destinations in an instant.
Roaming in Thailand: why an eSIM is a good idea
Thailand is not part of the European Union, so "roaming like at home" does not apply: your operator will charge you non-EU rates, which usually range from €10 to €15 per day or very limited data blocks that run out quickly. On a two-week trip, that's easily more than €100 just for connection. With an eSIM, you contract data in advance at a fixed price, with no surprises on your bill when you return and no scares from overconsumption.
How much does an eSIM for Thailand cost?
Plans start from €3.95 and you choose according to the days and usage. For a short getaway with maps and messaging, 1 GB for a few days is enough. For two or three weeks moving between Bangkok, Chiang Mai, and the islands, with social media and some video, calculate between 5 and 10 GB. If you are going to share the connection or work remotely, go for larger plans or ample data. It is always cheaper than roaming and buying a local card at the airport.
eSIM or SIM card in Thailand
The physical SIM card from AIS or True sold at Suvarnabhumi Airport works, but it involves queuing, showing your passport, and physically changing your chip, with the risk of losing your home one. The eSIM is digital: you install it before leaving Spain by scanning a QR and arrive with active internet. In addition, you keep your usual number operative to receive bank SMS or calls while using Thai data.
Does the eSIM work in Bangkok, Phuket, and Chiang Mai?
Yes. AIS, TrueMove H, and dtac coverage is solid in Bangkok, Chiang Mai, Phuket, Pattaya, Krabi, and Koh Samui, with good speed in urban and tourist areas. On small islands or jungle routes, the signal may drop, as with any local operator, but for 99% of your trip, you will have plenty of data for browsing, maps, and internet calls.
How do I activate the Thailand eSIM?
After purchase, you receive a QR code by email. You scan it from your mobile settings, the profile is installed, and you activate the data upon arrival in Thailand. All in a few minutes and without tools. If this is your first eSIM, follow our step-by-step eSIM guide and check that your phone is compatible beforehand. You will arrive connected and ready to enjoy your trip.
