eSIM for Bosnia and Herzegovina

Data for Sarajevo, Mostar and the road between them, installed before you arrive. Bosnia and Herzegovina is outside the EU roaming zone and on the Balkans plan and the Europe plan, so the day trip from Dubrovnik or the drive on to Belgrade stays on one eSIM.

10 other countries share the package with Bosnia and Herzegovina. A few of them:

Good to know

What's included, when it starts, and how to get connected.

Included countries
The Bosnia and Herzegovina plan covers Bosnia and Herzegovina only.
Local networks
In Bosnia and Herzegovina your eSIM connects to HT Eronet — 4G/5G where the network offers it.
When validity starts
Your package starts when your phone first connects to a network at the destination — not when you install it. Crossing a border does not restart it.
Installation and activation
Install the eSIM while you still have internet — at home or on Wi-Fi. Installation does not start validity. If you already have a onesim eSIM installed, a new package is added to it — no second installation. Setup guide
Calls and texts
onesim is data-only. Calls and messages work over data in apps like WhatsApp or FaceTime; your usual SIM keeps your number.
Support and refunds
Message the onesim support team from the app or the website. If a package cannot be installed or used, the refund policy explains what applies. Refund policy
Travel notes

Practical things, honestly.

The old bridge at Mostar over the Neretva
Phone

Bosnia is not in the EU, and an EU SIM charges its non-EU rate.

Roam-like-at-home stops at the Croatian border, and the drive from Split or Dubrovnik to Mostar crosses it. A package that covers both sides of the line is the simple answer; the Balkans plan and the Europe plan both do, and both carry on into Montenegro and Serbia.

Getting around

Everything is a drive, and the drives are slow and beautiful.

Sarajevo to Mostar is two and a half hours through the Neretva canyon by road, or by the daily train, which is one of the best rail views in Europe and runs to a timetable worth checking twice. Buses link everything else. A hire car from Croatia needs the green card and written permission to cross; ask when you book.

Money

The convertible mark, fixed to the euro, and cash almost everywhere.

The KM is pegged at about two to the euro, so the maths is easy. Euros are sometimes accepted in tourist spots at a round rate; the mark is better. Cards work in Sarajevo and Mostar’s hotels and larger restaurants; ćevabdžinice, markets, buses and most of the countryside are cash. ATMs are everywhere in the cities.

When to come

Mostar in July is 40°C and a coach park; May and October are Mostar.

The bridge and the old bazaar fill with day trippers from the coast between eleven and four in summer — stay the night and have the town at dusk. Sarajevo is pleasant from April to October, with the film festival in August; winter brings snow and the ski resorts at Jahorina and Bjelašnica, half an hour from the city.

Small things

The recent past is everywhere, and asked about with care.

Sarajevo’s siege and Mostar’s war are within living memory and visible on the buildings. Museums tell it well; people will too, if you ask rather than assume. Coffee is Bosnian, served in a džezva, and drunk slowly.

Coverage

Two packages cover it, and both keep going.

Bosnia and Herzegovina is on the Balkans plan and on the Europe plan. Either covers Sarajevo, Mostar and the road between; the difference is what happens next. The Balkans plan carries on into Serbia, Montenegro, Kosovo, North Macedonia, Albania and Bulgaria; the Europe plan carries on into Croatia and the EU. The Dubrovnik–Mostar–Sarajevo–Belgrade route fits either, since Croatia and Serbia are on both.

Coverage follows the local networks: strong in the cities and towns, good on the main roads, and thin in the mountains and the canyons between them, as it is for everyone. Download the route offline before the Neretva drive.

Bosnia and Herzegovina questions.

Answers about data, coverage and setup for Bosnia and Herzegovina.

No. Bosnia is outside the EU and the EEA, so roam-like-at-home does not apply and a European SIM charges its non-EU rate, capped by an agreement between the EU and the Western Balkan operators rather than free. The package on this page covers Bosnia and, on the Balkans plan, the whole region; on the Europe plan, Croatia and the EU as well.
