Does the eSIM also work on Thai islands such as Koh Samui or Phuket?

Yes. AIS provides 4G coverage on Thailand's main tourist islands, including Phuket, Koh Samui, Koh Phangan and Koh Lanta. In remote bays the signal can be weaker, but in towns and tourist areas you get stable reception.

Do I have to register or show the eSIM in Thailand?

No. Unlike local SIM cards, which you officially have to register with your passport in Thailand, a Reisechip eSIM skips this step completely. You install it before your trip and it is ready to use straight away.

How much data do I need for Thailand?

For a two-week tour with navigation, Grab use and social media, we recommend at least 5 GB. If you stream a lot or work on the road, 10 GB or an unlimited plan is the better choice, and prices in Thailand are very attractive.

Does the eSIM also work in northern Thailand, for example in Chiang Mai or Pai?

In Chiang Mai and most towns in the north you get 4G with no problem. In remote mountain regions such as around Pai or along the border with Myanmar, coverage can be more limited, but on standard travel routes the connection is reliable.

Can I use the Thailand eSIM for a stopover in a neighbouring country?

A Thailand eSIM is valid only on the Thai network. If you also need data in countries such as Malaysia, Vietnam or Cambodia, we recommend a regional Asia eSIM or separate eSIMs for each country.

How much does an eSIM for Thailand cost?

eSIM data plans for Thailand start at €1.69. You pay once for the data you choose — no contract, no monthly fee and no surprise roaming bill. Bigger data packs and longer validity cost more.

Is an eSIM cheaper than roaming in Thailand?

It depends on the destination. Inside the EU your German plan usually includes roaming, often with a fair-use data cap; outside the EU, roaming is typically charged per day or per megabyte, and a travel eSIM is usually much cheaper. With an eSIM you see the full price before you buy and pay only for your data pack.

Which mobile networks does the eSIM use in Thailand?

In Thailand the eSIM connects automatically to local networks such as AIS, TrueMove H, True Corporation (incl. DTAC), National Telecom (NT), on 4G/LTE and on 5G where it is available. Coverage in populated areas is around 90% of the population. Your phone always picks the strongest network nearby.

Will I keep my German phone number with an eSIM in Thailand?

Yes. Your German SIM and number stay active, and the travel eSIM runs alongside it as a data-only plan. You stay reachable on WhatsApp, iMessage or over Wi-Fi while browsing on the local network. Normal calls and texts still go through your German number, where roaming charges may apply.

Can I top up or extend my Thailand data plan?

Yes. When your data runs out or the plan expires, just buy another pack. The eSIM profile already on your phone stays in place, so there is nothing to reinstall and you stay online without a break.

Can I use the eSIM as a Wi-Fi hotspot in Thailand?

Yes. You can share the connection with a laptop, tablet or a travel companion through your phone's personal hotspot. Hotspot use comes out of the same data allowance, so choose a slightly larger pack if you plan to tether.

Should I install the eSIM before I leave or after I arrive?

Install it at home over Wi-Fi before you travel. The data plan switches on automatically when your phone joins a network in Thailand, so you are online the moment you land instead of hunting for airport Wi-Fi.

Why get an eSIM for Thailand?

Thailand is one of the most visited destinations in Asia for travellers from Germany, and mobile data there is not a luxury but a basic travel need. Booking Grab taxis, looking up temple opening hours, coordinating ferries between the islands: all of it needs a stable connection. There is public Wi-Fi in hostels and cafés, but on the move it is unreliable or slow. Local SIM cards are available at the airport, but they mean waiting, passport copies and manual setup. A Reisechip eSIM avoids all of that: you activate it from Germany, and as soon as you land in Bangkok you are online, on the AIS network, which covers 90% of the country, including the main islands such as Phuket, Koh Samui and Koh Tao. Your German number stays reachable throughout.
