Luxembourg is such a small country. Does data work well in the countryside and in the forests too?

Yes. Through the POST Luxembourg and Orange Luxembourg networks, nationwide coverage reaches 99%. You will usually pick up a 4G signal even in the dense forests of the Mullerthal Trail and the Ardennes region. The signal can be weak deep inside valleys or in some tunnel sections, though, so it is also a good idea to download offline maps in advance.

If I stay in Luxembourg and take a day trip to Belgium or Germany, do I need to switch to a different eSIM?

A single-country plan for Luxembourg may switch to roaming once you cross the border. If you choose a Europe-wide regional plan from Yeohaengyusim, you can use it in the same way in neighbouring countries such as Belgium, Germany and France as well as Luxembourg, with no extra cost, which is far more convenient. Be sure to check the list of countries a plan covers before you buy.

I plan to use an audio guide app and Google Maps a lot while sightseeing in Luxembourg City. How much data will I need?

For a half-day tour of the old town, using Google Maps and an audio guide app at the same time uses around 300–500MB a day on average. If you also want to upload photos to social media or stream video, it is best to allow for 1GB or more a day. Many travellers stay in Luxembourg only briefly, so you can also choose a short 3–5 day plan at Yeohaengyusim.

Can I find my way from Luxembourg airport to the city centre with the eSIM straight away?

Luxembourg International Airport (LUX) is only 6km from the city centre. If you install your Yeohaengyusim eSIM in advance, it connects to the local network automatically the moment you land, so you can use bus routes or taxi apps right away without hunting for Wi-Fi.

Can I get by in Luxembourg with a Korean card and no cash? What does having data make easier?

Card payment is very widespread in Luxembourg, so you can pay with a Korean Visa or Mastercard at most restaurants and shops. With data, you can translate Luxembourgish and French menus in real time with Google Translate, or check the routes of the free buses (public transport is free nationwide in Luxembourg!) in real time with a public transport app.

Does eSIM work in Luxembourg?

Luxembourg supports eSIM, and plans start from ₩1,944. Install it with the QR code you receive after buying, then just turn on data roaming after you arrive and you are connected straight away. There is no need to swap your SIM.

Travel eSIM or carrier roaming: which is cheaper for a trip to Luxembourg?

For a short trip or light data use, a travel eSIM is usually cheaper. Unlimited roaming from Korean carriers costs about ₩11,000–₩15,000 a day, but with an eSIM you can buy just the days of data you need in advance. For a short trip for one or two people, an eSIM has a big advantage; for a family or very heavy data use, compare carrier unlimited roaming too.

Which carrier network does a Luxembourg eSIM use?

In Luxembourg it connects automatically to local carrier networks such as POST Luxembourg · Orange Luxembourg · Tango (Proximus) (4G/LTE, 5G where supported). Population coverage is about 99%. It picks the network with the strongest signal automatically, so there is nothing to set up.

Can I keep using my Korean number while travelling in Luxembourg?

Yes. The eSIM works as a data-only second line, so your Korean SIM and number stay as they are. Use the Yeohaengyusim eSIM for data only, and keep receiving calls, texts and KakaoTalk on your Korean number.

Can I add to or extend my Luxembourg eSIM plan?

Yes. When you use up your data or the plan period ends, you can buy a new plan at any time. Keep using the eSIM profile you already installed; there is no need to install it again, so you carry on without interruption.

Can I use tethering (hotspot) in Luxembourg?

Yes. In Luxembourg you can share your eSIM data with other devices such as a laptop or tablet by tethering (hotspot). Shared data also comes out of your plan allowance, so if you tether a lot we recommend choosing a little more data.

Do I set up the eSIM before I leave or after I arrive?

We recommend installing it (registering the QR code) before you leave, while you have Wi-Fi. Data starts when you turn on data roaming after you arrive in Luxembourg. Just remember "set up before you leave, switch on when you arrive" and you can use the internet as soon as you land.

Luxembourg, a small gem of Europe, is a unique country where an old-world medieval fortress and a modern financial city exist side by side. The old town of Luxembourg City is beautiful enough to have been designated a UNESCO World Heritage Site, and the view of the city from the Adolphe Bridge holds its own against any European city. Small as it is, it borders three countries, Belgium, Germany and France, which makes it a perfect base for a multi-country trip. It is still an unfamiliar destination for travellers from Korea, but those who have been fall for its quiet elegance and want to go back. To get through a packed itinerary like this while using maps and translation apps freely, a stable data connection is a must. Install your Yeohaengyusim eSIM in advance and you can stay connected without interruption from the moment you leave Incheon to right after landing at Luxembourg airport.

Why an eSIM is essential for a Luxembourg trip

Luxembourg is so small that the whole country is only about ten times the area of Seoul, but thanks to the POST Luxembourg and Orange Luxembourg networks you can use 4G/LTE and 5G reliably anywhere in the country. You don't need to buy a separate SIM at the local airport: install your Yeohaengyusim eSIM in Korea beforehand and it connects automatically right after landing at Luxembourg International Airport. Luxembourg in particular sees many day-trippers heading to neighbouring Belgium, Germany and France, and not having to swap SIMs every time you cross a border makes things far more convenient. Even at natural attractions such as Vianden Castle and the Mullerthal Trail, network coverage reaches 99%, so there is no worry about getting lost even in the mountains. Because you keep your existing SIM and simply add the eSIM, you can still receive calls and messages on your Korean number at the same time, which is practical. Choose a Luxembourg plan at Yeohaengyusim and start your European trip with just one QR code.
