About this eSIM

Bosnia and Herzegovina is a small country whose mobile footprints broadly follow its internal political map, so signal strength can change noticeably within an hour's drive. That is normal here and it is not a fault. What matters for a traveller is that the main valleys and cities are well served, the mountains between them are not, and the country is compact enough that you are rarely more than an hour from a signal.

Getting online when you land

Sarajevo's airport sits in the Butmir suburb, close enough to the centre that the taxi ride is short, and it is where most visitors start. Others fly into Tuzla or Banja Luka, or arrive by road from Croatia toward Mostar and the Neretva valley, or by the long bus from Belgrade or Zagreb. Whichever way you come in, install the eSIM profile while you still have wifi at home and activate it once you have arrived, not before. Land borders are the one place worth being patient: registration can take a few minutes after a crossing while your phone finds a Bosnian network instead of holding onto the one it had on the other side.

The networks you'll be on

This eSIM runs on HT-ERONET, on 4G LTE, and your phone attaches to it automatically. There is no 5G on this plan, so plan on 4G as your ceiling in the cities and a step down to 3G on rural roads, which is still fine for maps and messaging.

Where coverage holds, and where it thins

Data is dependable through Sarajevo, Mostar, Banja Luka, Tuzla, Zenica and Bihac, along the M17 corridor that runs down the Neretva, and around the tourist towns like Trebinje, Jajce, Travnik and Pocitelj. It weakens the moment you go up. The Dinaric ranges swallow signal in the folds between peaks, so expect dead stretches driving the mountain roads toward Sutjeska national park, around Mount Bjelasnica and Jahorina outside ski season, in the canyons of the Vrbas and the Tara, and through the forested back roads of the Una valley. Rafting trips, hiking days and the scenic routes that make this country worth driving are exactly the places where you should not count on being reachable.

What you'll actually use data for here

Navigation, more than anywhere else in the region, because road signs vary in script between Latin and Cyrillic depending on which part of the country you are in, and route numbering is not always obvious. Live maps also help with the fact that the fastest road between two points is frequently not the most direct one. Beyond driving, travellers use data for translation, for bus timetables that are published across several competing station websites rather than one, and for reading up on the recent history that is written into the buildings around you in Sarajevo and Mostar. Messaging apps are how you will reach guesthouse owners, most of whom answer chat far faster than email. Coffee is a social institution here and plans get rearranged over it, so expect a fair amount of your day to be settled by message rather than decided in advance.

Before you fly

Install and label the profile at home, and switch your usual line to calls and texts only so it does not roam quietly in the background. Download offline maps covering the whole country, since it is small and the file is manageable, and include the mountain areas you plan to drive through rather than just the cities. Save your accommodation addresses and any booking references as screenshots. Take a power bank on any day involving the mountains, because searching for signal is one of the fastest ways to flatten a phone. If you plan to cross into Croatia, Montenegro or Serbia, remember this plan covers Bosnia and Herzegovina only, and your phone will need a different arrangement on the other side of the border.

Unlimited runs at full speed up to a fair-use limit, then continues slower.

Before you buy

Important to know

This is a data-only eSIM. It carries no calls or SMS on its own number.
Your existing number stays on your primary SIM, so calls and verification texts keep working.
Your phone must support eSIM, and some carrier-locked phones cannot install one.
Signal varies with location, terrain, congestion and your handset. Dense urban areas are consistently better served than remote ones.
The eSIM selects a host network automatically. You cannot pick or switch between them.
Unlimited plans run at full speed up to a fair-use limit, then continue at a reduced speed. Read the fair usage policy

Frequently asked questions

Does an eSIM work in Bosnia & Herzegovina?

Yes. Your Bosnia & Herzegovina eSIM connects automatically the moment you arrive, with no roaming fees and nothing to set up at the airport. The host networks it can use are HT-ERONET. Coverage runs on 4G LTE. There is no 5G on our host network in Bosnia & Herzegovina yet.

Do I get 5G in Bosnia & Herzegovina?

No. HT-ERONET do not yet offer 5G to visitors in Bosnia & Herzegovina, so your eSIM connects over 4G LTE or slower. Anyone claiming 5G for this destination is quoting a spec sheet, not the network you will actually get.

Is there 5G in Bosnia and Herzegovina?

Not yet. All three operators, BH Telecom, m:tel and HT Eronet, have run 4G since their licences were issued in April 2019. As of 2025 no 5G licences had been awarded, and the regulator was expected to open a 5G tender in 2026. Your eSIM uses HT Eronet's 4G LTE network, which is enough for maps, messaging and video calls.

How long is the free wifi at Sarajevo airport?

Sarajevo International Airport's PASSENGER ZONE network is free, but limited to about 15 minutes in arrivals and the main hall, and roughly an hour in departures. You accept the terms with one tap, and longer access needs a voucher bought from an airport café or bar. An eSIM switched on as you land avoids that limit.

Does Uber or Bolt work in Sarajevo?

No. Visitor guidance for Sarajevo states that neither Uber nor Bolt operates there. You book licensed taxis from firms such as Sarajevo Taxi, Yellow Taxi or Red Taxi, recognisable by the TAXI roof sign and TA number plates. Fares are paid in cash in convertible marks. At the airport, agree the price before you get in.

Can I pay with euros in Bosnia and Herzegovina?

Generally not in shops, restaurants or cafés, which price and take payment in convertible marks (KM). Cards are accepted in shopping centres and better restaurants, but often not in cafés, old-town shops in Baščaršija, for parking or on public transport. Carry some marks, and use your banking app on mobile data to keep track of card payments.

Is it safe to follow map shortcuts when hiking in Bosnia?

Not off marked routes. The UK Foreign Office says leftover mines are still a risk in rural areas, woods, orchards, along road verges and near former front lines. It advises not leaving roads or paved areas without an experienced guide. Download offline maps showing marked trails, stick to them, and ignore app shortcuts down unmarked tracks.

How much data do I need for 7 days in Bosnia & Herzegovina?

For 7 days in Bosnia & Herzegovina, Viasimo sells 1 GB for $3.29 and unlimited data for $34.00. Our sizing recommendation, not a measurement: maps, messaging and the occasional lookup, about 1 GB a week; maps, social, photos and some browsing, about 3 to 7 GB a week. The data calculator on this site works it out from how you actually use your phone.

Know before you go

Bosnia & Herzegovina: what to know before you land

Bosnia and Herzegovina has three mobile operators, each rooted in a different part of the country, and none of them had launched commercial 5G by 2025. Your eSIM uses HT Eronet's 4G LTE network. Sarajevo airport's free wifi cuts off after 15 minutes in arrivals, and there is no Uber or Bolt, so mobile data is what keeps you organised.

Sarajevo airport (SJJ) wifi and the taxi rank

Sarajevo International Airport (SJJ) offers free wifi on a network called PASSENGER ZONE. You connect and tap "I Agree – OK", but the free time is short: about 15 minutes in the arrivals area and main hall, and roughly an hour in the departures zone. After that you need a voucher, which you buy from one of the airport's food and drink outlets. If you switch on your eSIM as you land, you can skip that limit completely.

Having data matters at the taxi rank. The UK Foreign Office notes that drivers at Sarajevo airport sometimes quote a "fixed price" or add a luggage charge. It advises agreeing the fare before you set off, or pre-booking an established taxi company. Licensed taxis in Sarajevo have a TAXI sign on the roof and number plates beginning with TA. Call a firm or message your accommodation from the arrivals hall so a car is waiting, rather than negotiating at the door.

HT Eronet, BH Telecom and m:tel: who runs what

The mobile market follows the country's internal divisions. According to the US government's 2025 commercial guide, BH Telecom is based in Sarajevo and had about 42% of mobile subscribers at the end of 2024. m:tel, based in Banja Luka and owned by Telekom Srbija, covers Republika Srpska with around 36%. HT Eronet, based in Mostar and serving the Croat-majority areas of the Federation, had about 21%. BH Telecom also announced in 2025 that it would buy Telemach's assets in the country.

Your eSIM connects to HT Eronet on 4G LTE. All three operators received 4G licences in April 2019. No 5G licences had been issued as of 2025, and the regulator was expected to open a 5G tender in 2026. That means no traveller will find 5G here for now, whichever SIM they use.

Near the Croatian border, in western Herzegovina or along the road to Neum and Dubrovnik, your phone may briefly show a Croatian network. If data stops, check which network the eSIM has attached to.

Cash-only taxis and no ride-hailing in Sarajevo

A 2023 practical guide for visitors to Sarajevo says plainly that Uber and Bolt do not operate there. You book taxis with firms such as Sarajevo Taxi, Yellow Taxi or Red Taxi, usually by phone, and pay in cash in local currency. Your eSIM is data-only, so use your home SIM for those calls, or ask the firm whether it takes bookings over WhatsApp or Viber.

The currency is the convertible mark (KM, or BAM). The same guide notes that shops, restaurants and cafés generally do not take euros. Cards work in shopping centres and the better restaurants, but often not in cafés, in the Baščaršija old-town shops, for parking or on public transport. Bus and tram tickets are cheaper from a kiosk than from the driver, and you have to punch them when you board.

If you take a taxi across the country, be aware of a detail the Foreign Office flags: some drivers from Republika Srpska refuse trips into the Federation, and some Federation drivers refuse trips the other way. Check before you set off.

Mine risk off the paths around Sarajevo and rural roads

Mine clearance has made populated areas and main roads largely safe. The Foreign Office warns, however, that risk remains in rural and less populated areas, especially near former front lines, along road verges, in open countryside, woods and orchards, around abandoned or ruined buildings and on untarred tracks. Its advice is not to step off roads and paved surfaces without an experienced guide.

This changes how you should use your phone outdoors. Download offline maps that show marked hiking trails before you leave signal, and stay on them. Don't follow a map app's shortcut down an unmarked track, and don't wander off a lay-by to take a photo. For hikes on Bjelašnica, Jahorina or Igman, use a local guide or a marked mountain route, and share your plan with your accommodation over WhatsApp before you leave reception.

The single emergency number in Bosnia and Herzegovina is 112, which also covers wildfires. Because the eSIM has no calling, make that call from your home SIM, which can reach emergency services while roaming.

7-day itinerary

Seven days in Bosnia and Herzegovina: Sarajevo, Mostar, Herzegovina and Jajce

A loop from Sarajevo by the scenic Neretva railway to Mostar, with day trips into Herzegovina's waterfalls and Ottoman towns, then north to the mills and falls of Jajce and back through Travnik. Best with a hire car for days four to six; buses also cover most of it.

Length: 7 days
Bases: 3

When to go May to June and September to October are warm without the heat of a Herzegovina summer, when Mostar regularly passes 35°C; winter brings snow to Sarajevo and the mountains and a short ski season on Jahorina and Bjelašnica.

Day 1 Sarajevo

Sarajevo: Baščaršija and the old town

Sarajevo airport (SJJ) is about 12 km from the centre; agree the taxi fare before you set off or pre-book.

Start at the Sebilj fountain in Baščaršija, the Ottoman-era bazaar, and walk its lanes of coppersmiths. Visit the Gazi Husrev-beg Mosque and its courtyard, then cross towards Ferhadija street, where a marker in the pavement shows where the Ottoman and Austro-Hungarian parts of town meet. Look in at the Old Orthodox Church and the Cathedral of Jesus' Heart. Finish at the Latin Bridge, near the spot where Archduke Franz Ferdinand was shot in 1914, and the small museum beside it.

Signal HT Eronet 4G works across central Sarajevo; this eSIM connects on 4G rather than 5G, which is fine for maps and messaging in the old town.
Day 2 Sarajevo

Siege history and Mount Trebević

Visit the War Childhood Museum or Galerija 11/07/95 to understand the 1990s, then take a taxi to the Tunnel of Hope museum near the airport, where a short stretch of the wartime supply tunnel is open. In the afternoon, ride the Trebević cable car from the riverside up the mountain and walk to the abandoned 1984 Olympic bobsleigh track, keeping to paved paths. Come down for sunset at the Yellow Fortress viewpoint over the old town.

Signal Good 4G in the city and around the Tunnel museum; on Trebević the signal is weaker away from the cable car station, and you must not leave marked paths because of leftover mines.
Day 3 Mostar

The Neretva railway to Mostar

Train Sarajevo–Mostar takes about 2 hours, with two departures a day (check the current timetable); the bus takes about 2½ hours.

Take the morning train south from Sarajevo through the mountains and along the Neretva gorge, passing Konjic and the Jablanica reservoir. In Mostar, walk to the Old Bridge (Stari Most), rebuilt after the war and now a UNESCO site, and watch the club divers jump from it into the river. Explore the Kujundžiluk bazaar, climb the minaret of the Koski Mehmed-Pasha Mosque for the classic view of the bridge, and visit the Museum of War and Genocide Victims or the Old Bridge Museum.

Signal The railway runs through tunnels and a deep gorge, so expect gaps; Mostar is HT Eronet's home city and has solid 4G across the old town.
Day 4 Mostar

Blagaj, Počitelj and Kravica

Blagaj is about 20 minutes from Mostar, Počitelj about 45 minutes, and Kravica about 45 minutes; a hire car or tour makes this one day.

Drive to Blagaj to see the dervish house (tekke) built against the cliff at the source of the Buna river; women need a headscarf to enter. Continue south to Počitelj, a fortified Ottoman village climbing a hillside above the Neretva, and walk up to its tower. In the afternoon, swim below the Kravica waterfall near Ljubuški, a wide curtain of falls into a pool that is busiest in July and August.

Signal Western Herzegovina is HT Eronet's strongest area, so 4G is good in all three places; close to the Croatian border your phone may briefly show a Croatian network.
Day 5 Jajce

North to Jajce and the Pliva waterfall

About 2½–3 hours by road from Mostar; the bus takes 3½–4 hours.

Drive north through Prozor and the hills of central Bosnia to Jajce. See the Pliva waterfall, where the river drops into the Vrbas right below the old town, then climb to the medieval fortress and visit the catacombs carved for the Bosnian nobility. Walk or drive a few kilometres to the Pliva lakes to see the row of small wooden watermills (mlinčići) on the water. Visit the AVNOJ museum, where Yugoslavia's post-war federation was founded in 1943.

Signal 4G is fine in Jajce town but drops on the mountain roads north of Prozor; download offline maps before leaving Mostar.
Day 6 Sarajevo

Travnik and back to Sarajevo

Jajce to Travnik takes about 1 hour by road; Travnik to Sarajevo about 1½ hours.

Drive east to Travnik, once the seat of the Ottoman viziers of Bosnia. Walk to the Many-Coloured Mosque, with its painted facade, and the hillside fortress above the town. See the tombs of the viziers on the main street and visit the birth house of Ivo Andrić, the Nobel Prize-winning writer. Stop at the Plava Voda springs for lunch, then continue to Sarajevo.

Signal 4G holds in Travnik and along the main road to Sarajevo, with brief drops in the valleys around Vlašić.
Day 7 Sarajevo

Vrelo Bosne and departure

Tram from the centre to Ilidža takes about 30–40 minutes; the airport is a short taxi ride from Ilidža.

Take the tram to Ilidža and walk or ride a horse-drawn carriage along the Velika aleja avenue to Vrelo Bosne, the park at the springs of the Bosna river, with its streams and wooden bridges. Back in the city, walk along the Miljacka to the restored Vijećnica, the former city hall and library that burned in 1992, and visit its exhibition. Have a final Bosnian coffee in Baščaršija before your flight.

Signal Reliable 4G at Ilidža, Vrelo Bosne and the airport road; the airport's free wifi in departures lasts about an hour.

Staying connected on this route

Download offline maps that show marked trails before Trebević, Jajce and other rural areas, and never follow an app shortcut onto an unmarked track.
Near the Croatian border in Herzegovina, check your phone has not switched to a Croatian network if data stops.
Book taxis by phone from your home SIM or by WhatsApp, as there is no Uber or Bolt.
The Sarajevo–Mostar railway has tunnels and gorge sections with no signal, so save your ticket and route first.
