Bosnia and Herzegovina has three mobile networks: BH Telecom (the largest), m:tel and HT Eronet. Our eSIM for Bosnia and Herzegovina runs on the HT Eronet network, with 3G and 4G speeds. HT Eronet is strongest in Herzegovina, around Mostar, Blagaj and Medjugorje, and also covers Sarajevo with 4G. In the mountains and on some roads between towns the speed can drop or the signal can briefly fall away, so expect slower data on remote mountain routes. Networks: HT Eronet.
For a city trip combining Sarajevo and Mostar, around 3 GB per week is enough. On a road trip through the mountains with lots of navigation, take 5 GB or more and download offline maps before you set off.
Bosnia and Herzegovina is not in the EU and not yet part of the EU roam-like-at-home area, so free EU roaming from your home plan does not apply. Most providers charge extra for data there, which makes a fixed eSIM bundle the easier way to stay online.

Yes. Our eSIM gives you instant mobile data in Bosnia and Herzegovina on the local networks, with no roaming fees. Your phone needs to support eSIM and be carrier-unlocked.
It depends on your trip. For mostly maps and messaging, 1 to 3 GB is plenty. If you use navigation, social media and some streaming, plan for roughly 1 GB every two to three days.
Right after payment. You receive a QR code on screen and by email immediately. It is best to install it at home over Wi-Fi before you leave.
Yes. Your own SIM stays in your phone for calls and texts. The eSIM runs alongside it, purely for mobile data in Bosnia and Herzegovina.
The cheapest eSIM for Bosnia and Herzegovina at esimzu starts from €2,99, with a lowest-price guarantee. You pay in euros by Bancontact, card or crypto and receive the eSIM instantly by QR code, with no app or physical SIM card.
No. Bosnia and Herzegovina is not an EU member and falls outside the roam-like-at-home rules. In 2026 the European Commission proposed negotiations to bring the Western Balkans into roam-like-at-home, but nothing has been agreed yet and there is no start date. For now your provider will usually charge extra for data there.
The eSIM uses HT Eronet, one of the three national networks. It is strongest in Mostar and the rest of Herzegovina and also offers 4G in Sarajevo. On arrival, turn on data roaming for the eSIM line. It then connects by itself, so there is no network to pick manually.
With an EU plan your data works in Croatia as at home, but that stops as soon as you cross into Bosnia and Herzegovina. For a day trip to Mostar the 1 GB plan for 7 days is usually enough for maps, messages and a few photos. The eSIM only works in Bosnia and Herzegovina, so in Croatia you keep using your own plan. If you drive the coastal road through Neum, remember that this short stretch is Bosnian territory, so your phone may connect to a Bosnian network there.
Most of the route via Mostar runs through Herzegovina, where HT Eronet is strongest. In the Neretva canyon and on mountain passes the speed can drop or the signal can briefly fall away, so download offline maps before you leave.
