Can I use the internet the moment I reach Budapest Airport?

Yes. If you install your Yeohaengyusim eSIM before departure Korea, it links up automatically with the Magyar Telekom network right after landing at Budapest Ferenc Liszt International Airport. You can use map and transport apps right away, without waiting for airport Wi-Fi or queuing to buy a SIM.

Can I use the eSIM when I travel from Hungary to neighbouring countries such as Austria or Czechia?

If you choose one of the Europe-wide plans sold by Yeohaengyusim, you can use the same data not only in Hungary but also in neighbouring countries such as Austria, Czechia and Slovakia, at no extra cost. If your Eastern Europe itinerary takes in several countries, we recommend a multi-country Europe plan.

Does the internet work well at Lake Balaton or in regional towns such as Eger?

Coverage across Hungary is very high, at about 96%. You can use the internet reliably at 4G/LTE speeds at the sights around Lake Balaton and in central Eger too. However, the signal may weaken in very remote mountainous areas.

Is the data connection stable indoors too, in places such as the Széchenyi Baths or ruin bars?

Magyar Telekom and Yettel Hungary also have good indoor coverage at the main sights in central Budapest. The 4G connection is generally stable inside the Széchenyi Baths building and inside ruin bars too. Uploading photos straight away or sharing your location with friends in real time is no problem.

Can I use KakaoTalk or make video calls to Korea from Hungary?

Yes. Once you are connected to data with your Yeohaengyusim eSIM, you can use all internet-based messengers and video call apps, such as KakaoTalk, FaceTime and Zoom. The time difference between Hungary and Korea is about 8 hours (7 hours during daylight saving time), so it helps to agree on a time for calls in advance.

Does eSIM work in Hungary?

Hungary supports eSIM, and plans start from ₩1,492. 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 Hungary?

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 Hungary eSIM use?

In Hungary it connects automatically to local carrier networks such as Magyar Telekom · Yettel Hungary · One (formerly Vodafone) (4G/LTE, 5G where supported). Population coverage is about 96%. 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 Hungary?

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 Hungary 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 Hungary?

Yes. In Hungary 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 Hungary. Just remember "set up before you leave, switch on when you arrive" and you can use the internet as soon as you land.

Budapest, Hungary, where Buda and Pest face each other across the Danube, is a city so beautiful that it is called 'the Paris of Eastern Europe'. From the golden night view of the Parliament Building and the warm waters of the Széchenyi Baths to the wide-open view from Fisherman's Bastion—this is a place where every single photo becomes a work of art. Add nearby small towns such as Esztergom and Visegrád, and there is no end of things to see. To really enjoy a trip to Hungary, you need a reliable internet connection so you can find your way down every alley with Google Maps and look up good restaurants and thermal bath information in real time. If you install a Yeohaengyusim eSIM in Korea before departure, your map app works right away right after landing at Budapest Airport, and you can check even complicated public transport routes without a hitch. Start your trip to Europe with just your smartphone, with no need to swap SIM cards.

Why an eSIM really helps for a trip to Hungary

Hungary is a hub for travel in Eastern Europe, and many Korean travellers love to visit it on a route that combines it with Vienna in Austria or Prague in Czechia. On an itinerary that crosses borders, swapping in a local SIM every time is a real hassle. Yeohaengyusim has many eSIM plans that cover several European countries, so even a multi-country itinerary that includes Hungary can be handled with one eSIM. In central Budapest, Magyar Telekom and Yettel Hungary have dense 4G/LTE and 5G networks, so you can stream music inside the thermal baths or post photos to social media in real time from a ruin bar without interruption. Even when you leave the city centre to visit Lake Balaton or regional towns such as Eger, 96% nationwide coverage means you can travel without worrying about the internet. You don't need to queue in front of a roaming booth at the airport, or to go to the trouble of opening a SIM pack from a local convenience store and installing it. Finish the installation in Korea with a single QR code and head straight off to Hungary.
