Does the internet work well in Sarajevo and Mostar?

In central Sarajevo and Mostar, 4G LTE works relatively reliably. However, the signal may weaken or drop on the mountain roads between the two cities or in outlying areas, so we recommend saving important maps and information offline in advance.

Do I really need translation or map apps when travelling in Bosnia and Herzegovina?

Yes, we strongly recommend them. Bosnian (Bosniak) uses both the Cyrillic and Latin alphabets, and in many places English is not spoken. Google Translate and Google Maps are essentials for exploring. You need data connected through an eSIM to use these apps in real time.

How do I exchange money in Bosnia and Herzegovina? Can I find information online?

The local currency is the 'Bosnian mark (BAM)'. You get better rates at exchange offices in town (Mjenjačnica) or bank ATMs than at the airport. When you are online with a Yeohaengyusim eSIM, you can check live exchange rates and find nearby ATMs right away.

Is there a data connection near Mostar's Stari Most (Old Bridge)?

Mostar's old town and the area around Stari Most have well-developed tourist infrastructure, so you can generally get 4G LTE. You should have no trouble posting your photos straight to social media or looking up nearby restaurants.

Do I need a visa to enter Bosnia and Herzegovina?

Korean passport holders can enter Bosnia and Herzegovina visa-free for up to 90 days. However, your passport must be valid for at least 6 more months when you enter, and you may need a return ticket and proof of travel funds, so check before departure.

Does eSIM work in Bosnia and Herzegovina?

Bosnia and Herzegovina supports eSIM, and plans start from ₩2,999. 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 Bosnia and Herzegovina?

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 Bosnia and Herzegovina eSIM use?

In Bosnia and Herzegovina it connects automatically to local carrier networks such as BH Telecom · HT Eronet · m:tel (4G/LTE, 5G where supported). Population coverage is about 80%. 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 Bosnia and Herzegovina?

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 Bosnia and Herzegovina 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 Bosnia and Herzegovina?

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

Bosnia and Herzegovina, the hidden gem of the Balkans, is a destination drawing more and more attention among Korean travellers. The alleys of Sarajevo, where traces of the Ottoman Empire remain intact, Mostar's Stari Most arching gracefully over the emerald Neretva River, and beautiful scenery set in unspoilt nature that rivals the Plitvice canyons all welcome travellers. With its unique blend of Eastern and Western cultures and some of the most reasonable prices in Europe, it is a country that draws you in the more you get to know it. Maps and translation apps are essential when you explore unfamiliar alleys and seek out local restaurants, and with one Yeohaengyusim eSIM you can use the internet without worry on arrival. Install it before departure, with no SIM swap, and connect the moment you set foot there.

Why you need an eSIM in Bosnia and Herzegovina

Many places in Bosnia and Herzegovina still lack fully developed travel infrastructure. You can buy a local SIM at Sarajevo International Airport, but communicating in English is difficult and activation is complicated, so it is easy to waste time from day one. A Yeohaengyusim eSIM, on the other hand, connects automatically to the BH Telecom network the moment you land in Bosnia and Herzegovina, as long as you install it before departure Korea by scanning the QR code you received in the app or by email. You can look up cafés in real time as you walk through Baščaršija, Sarajevo's old town, and check your route on Google Maps even on the bus to Mostar. Coverage may be weak in mountain areas and small towns, but at the main sights and in city centres you can enjoy stable internet at 4G LTE speeds. Another big advantage is that you can use as much as you like within your set data allowance, without worrying about roaming bill shock. You keep your existing Korean number as it is, so receiving KakaoTalk messages and calls is no problem.
