Why choose an eSIM for Thailand?
Thailand is one of the world’s most popular travel destinations and attracts millions of visitors every year. In recent years, eSIMs have become a practical alternative to traditional SIM cards and are increasingly popular with travelers.
With the growing number of eSIM providers, however, finding the best option can be tricky. That is why we took a close look at the different networks, carried out local tests and put together the best eSIM options for Thailand. So if you are planning a trip to Thailand or need an eSIM for mobile internet, you will find all the key information here to make the right choice.
Thailand SIM card: passport or ID required
Buying a local SIM card in Thailand often requires showing your passport. An eSIM for Thailand is therefore the perfect solution: fast, uncomplicated and activated directly on your phone. And if you buy it in advance while still in Germany, you can skip comparing providers at the airport. You can also leave your SIM card in your smartphone and remain reachable via WhatsApp. We offer eSIM packages for 3, 7, 15, 21 and 30 days with unlimited mobile data.
AIS vs. dtac vs. Truemove – Which network is best?
Thailand has three major mobile network providers: AIS, dtac and Truemove H. As the graphic already shows, Thailand has consistently very good network coverage, with at least 4G/LTE available almost nationwide. Reception is excellent, especially in cities and on tourist islands.
AIS – Thailand eSIM with strong 5G coverage
AIS offers the broadest network coverage in the 5G range. If you are looking for an eSIM that offers 5G coverage even in more remote places, AIS is a strong choice. However, its plans are often slightly more expensive than those of its competitors.
dtac – Thailand eSIM with top deals for heavy users
dtac often offers the cheapest data packages with generous data allowances. Right now, for example, you can get 50 GB for 10 days for only €8.99 from us, including 100 free minutes for local calls.
👉 If you are staying longer than 10 days, you can simply book several 50 GB packages or choose a 30-day eSIM. Most travelers rarely need more than 5 GB per day. 😊
Truemove – Unlimited eSIM with excellent coverage
For our unlimited eSIM packages, we chose Truemove as the main network. Why? Because it offers very good network coverage while also being more affordable than AIS. That makes Truemove the perfect middle ground between top coverage and fair prices.
Our recommendation: If you are looking for an unlimited data eSIM for Thailand, you can start browsing from €2.17 per day.
Practical tips for using an eSIM in Thailand
Before activating your eSIM, make sure your smartphone is eSIM-compatible. Most modern iPhones, Google Pixel devices and many Samsung models already support eSIMs. We also recommend buying and activating your eSIM before departure so you are online as soon as you land. A stable internet connection helps not only with navigation, but also with spontaneous accommodation or hostel bookings.
No matter which network you choose, with an eSIM for Thailand you can get your phone online in just a few minutes, with no SIM card swap and no local registration.
Enjoy Thailand! 🇹🇭
