SIM cards and internet in Bosnia and Herzegovina

Getting online the moment you land

Sarajevo is an easy city to stay connected in, but it’s worth planning this before you board rather than assuming your phone will simply work the way it does inside the EU. Bosnia and Herzegovina sits outside the EU, the EEA and the Schengen area, so the roaming rules you’re used to from an Italy-Croatia-Slovenia trip don’t carry over automatically. The fix is straightforward: either buy a local prepaid SIM on arrival, or lean on wifi, which is genuinely reliable across most of the accommodation and cafés a visitor actually uses in the city centre.

Most travellers land at Sarajevo International Airport (SJJ), a short hop from the centre — see getting to Sarajevo and Sarajevo Airport to city centre for the transfer itself — and buy a SIM once they’ve checked in, rather than hunting for one airside. If you need connectivity from the moment your flight lands, ask your accommodation ahead of time whether an operator counter is currently open inside the terminal, since small kiosks there come and go more often than the shops on Ferhadija or around Baščaršija.

Why your European roaming plan may not just work here

This is the single most common source of confusion for visitors arriving from elsewhere in Europe. Inside the EU and EEA, “roam like at home” rules mean your normal data and call allowance travels with you at no extra cost. Bosnia and Herzegovina is a candidate country — accession talks opened in March 2024 — but it is not a member state, not in the EEA, and not in Schengen. None of that EU roaming regulation applies here by default.

In practice this means:

• A plan that roams free in Croatia, Slovenia or Austria may charge full international rates the moment you cross into Bosnia and Herzegovina, or simply refuse to connect to data.
• Some operators sell add-on packages that specifically include the Western Balkans (Bosnia and Herzegovina, Serbia, Montenegro, North Macedonia, Albania) — but this is operator- and plan-specific, not a blanket right.
• The safest approach is to check your operator’s app or website before you leave, rather than discovering the gap with a data bill after the fact. If in doubt, assume standard international roaming rates apply and budget for a local SIM instead.

This is the same border logic that applies to your Schengen 90/180-day count, covered in visa and entry rules for Bosnia and Herzegovina: the country sits genuinely outside the EU’s systems, for better (days here don’t burn your Schengen clock) and for worse (your phone plan doesn’t recognise the border either).

Buying a prepaid SIM: what to expect

Three national operators cover the country, and all three sell short-stay or tourist SIM packages aimed at visitors:

Operator	Bosnian/local name	Where to buy in Sarajevo
BH Telecom	BH Telecom	Shops around Ferhadija and Baščaršija, plus kiosks in shopping centres
m:tel	m:tel	Operator shops in the centre and in Ilidža
HT Eronet	HT Eronet	Fewer outlets in Sarajevo itself; stronger presence toward Mostar and Herzegovina

None of the three has a meaningful coverage advantage inside Sarajevo or along the main roads to Mostar, Trebinje, Jajce or the ski resorts — pick whichever shop is closest or whichever queue is shorter. Coverage from any of them thins out in the high mountains: don’t expect a strong signal at Lukomir, deep in Perućica forest inside Sutjeska National Park, or on some stretches of the Bjelašnica plateau above Umoljani.

Buying a SIM is quick. Bring your passport — every operator registers prepaid SIM cards to an ID document, and staff will ask for it before they’ll activate the card. A photo of your passport on your phone isn’t always accepted; carry the physical document. Staff at operator shops in the centre are used to serving visitors and generally speak enough English to walk you through the available data bundles.

Kiosks and newsagents around Baščaršija sometimes stock SIM starter packs too, which can be quicker than a full shop visit, though activation and registration still go through the same passport check. If your hotel or apartment host is helpful, ask them — many are happy to point you to whichever shop is currently fastest, since this changes with staffing and queues more than with any fixed rule.

a half-day tour tracing the rise and fall of Yugoslavia through Sarajevo’s 20th-century sites is a good example of a booking worth having data for — confirmation messages, meeting-point pins and last-minute changes from the operator all arrive by phone, and a working SIM or hotel wifi makes that painless rather than a scramble at the meeting point.

SIM registration and the separate foreigner registration

Don’t confuse two unrelated registration steps that happen to land in the same first day or two of a trip. Registering your SIM card to your passport at the point of purchase is a one-off requirement from the mobile operator, done once, at the shop counter. Separately, Bosnia and Herzegovina requires visitors to register with the foreigners’ service within 24 to 48 hours of arrival, depending on the canton — often called the “bijeli karton” or prijava boravka.

Hotels and hostels handle this automatically as part of check-in; if you’re staying with a private host or in an apartment booked informally, ask for written confirmation that it’s been done, since it isn’t always handled without being asked. Neither registration affects the other, and neither is optional.

Wifi as the reliable fallback

If your stay in Sarajevo is short, or your itinerary stays mostly within the city, wifi alone can cover most needs without a SIM at all. Hotels, hostels and apartments in the areas visitors actually stay — around Baščaršija, Ferhadija, and the newer part of town toward Marijin Dvor — generally have working wifi as standard, and it’s reasonable to ask about speed and reliability before booking if you’ll be working remotely. Most cafés will share their network with paying customers; it’s polite to ask rather than assume, particularly in smaller, independent places rather than chains.

Wifi is also the more dependable option the moment you’re inside a museum, gallery or restaurant with thick stone walls, where mobile signal indoors can be patchier than the street outside suggests. If you’re planning a working day between sightseeing, choosing where to stay in Sarajevo with confirmed wifi is a more useful filter than chasing the fastest mobile data plan.

Calling within Bosnia and Herzegovina: the dialling codes you’ll actually use

Even travellers who rely entirely on wifi and messaging apps tend to need a phone number at some point in Bosnia and Herzegovina — booking a driver for an early departure, calling ahead to confirm a rafting trip is running, or reaching an apartment host who doesn’t check messages. The country code is +387. Area codes then identify the city:

City	Area code
Sarajevo	033
Mostar	036
Banja Luka	051

To call a Sarajevo landline from abroad, dial +387, then 33, then the local number (the leading 0 in a domestic area code is dropped when you add the country code). The same pattern applies for Mostar and Banja Luka. This matters more than it might sound: taxi companies, smaller guesthouses and some tour operators in Bosnia and Herzegovina still rely on a phone call rather than an app or online form, particularly outside Sarajevo itself.

If you’re arranging a day trip to Mostar and Herzegovina with lunch included or confirming pickup times for transport to Mostar, having the right dialling format ready saves a confused call.

For calls within Sarajevo itself, locals typically just dial the seven-digit local number without the area code; you’ll only need the full 033 prefix when calling from another Bosnian city or from a mobile registered elsewhere.

Data on day trips: where coverage gets patchy

Sarajevo itself has solid 4G coverage from any of the three operators, as do the main roads out to Mostar, Trebinje, Jajce and Banja Luka. Where it gets less reliable is exactly where you might want it most — off the main road, in the mountains:

• Lukomir, the highest permanently inhabited village in the country at around 1,469 metres, has patchy coverage at best; don’t rely on being reachable there.
• Perućica, the primary forest inside Sutjeska National Park, has no meaningful signal — one more reason a guide is required for that section regardless of connectivity.
• Rakitnica Canyon and the wider Bjelašnica-Umoljani hiking area drop in and out depending on which ridge you’re on.
• Konjic, home to Tito’s Cold War bunker, and the road toward Jablanica hold a signal reasonably well, being on a main route.

None of this should change how you plan a hike — the operative safety rule in Bosnia and Herzegovina’s countryside is to stay on marked trails and in areas that see regular foot traffic, because of the ongoing risk from unexploded landmines in unmarked ground, not because of phone signal. But it’s worth downloading offline maps and telling your accommodation your rough plan before setting out for a guided hike to Lukomir or a day exploring Rakitnica Canyon, rather than counting on being able to look something up mid-route.

eSIM options and topping up

eSIM availability from Bosnian operators has been inconsistent and shop staff aren’t always the fastest way to confirm current options, so if an eSIM matters to your setup, check directly with BH Telecom, m:tel or HT Eronet’s own websites, or a reputable international eSIM provider that lists Bosnia and Herzegovina coverage, before you travel. A physical prepaid SIM remains the more dependable route for most visitors and is what shop staff are set up to sell quickly.

Topping up a prepaid SIM is usually possible at the same shops and kiosks that sell the starter packs, and some operators support top-ups through their own app once you’re registered. If you’re only in the country for a few days, buying a bundle sized to your trip length up front is simpler than topping up partway through.

A practical route through the first day

For most visitors, the sequence looks like this: land at Sarajevo Airport, take the airport transfer into the city centre, check into your accommodation and let them run your foreigner registration, then walk to an operator shop near Ferhadija or Baščaršija with your passport for a SIM — or simply confirm the wifi works and decide you don’t need one. Either way, note down the dialling format above before you need to call anyone, since it’s easy to forget the +387 prefix in the moment.

From there, connectivity stops being something to think about, whether you’re confirming a bike tour that includes entry to the Tunnel of Hope, joining a walking route through Sarajevo’s traditional mahala neighbourhoods, or simply checking public transport in Sarajevo on the way to dinner.

SIM cards and internet in Bosnia and Herzegovina: FAQ

Do EU roaming allowances work in Bosnia and Herzegovina?

Not automatically. Bosnia and Herzegovina is outside the EU, the EEA and Schengen, so the EU’s “roam like at home” rules don’t extend here even if your last stop was Croatia or Slovenia. Some operators sell add-on packs that include the Western Balkans, but this varies by provider and plan — check with your operator before you arrive rather than assuming coverage.

Can I buy a SIM card at Sarajevo Airport?

Operator counters and shops are easy to find in the city centre, a short taxi or tram ride from the airport, and that’s where most visitors buy one. If you want to be online from the moment you land, ask your accommodation in advance whether an operator kiosk operates inside the terminal, since airport-level retail changes more often than shops in Baščaršija or Ferhadija.

What do I need to buy a prepaid SIM in Bosnia and Herzegovina?

Your passport. Registering a SIM card to an ID document is standard practice at every operator shop and kiosk, and staff will ask for it before activating the card, so carry it rather than a photocopy or a photo on your phone.

Which mobile operators work in Bosnia and Herzegovina?

The three national operators are BH Telecom, m:tel and HT Eronet. All three sell tourist or short-stay prepaid packages with data, and coverage in Sarajevo and along the main roads to Mostar, Trebinje and the ski resorts is solid from any of them. Coverage thins out in the high mountains — Lukomir, Sutjeska’s Perućica forest, and stretches of the Bjelašnica plateau — regardless of operator.

Is wifi reliable in Sarajevo?

Yes, in the areas visitors actually use. Hotels, hostels and apartments in and around Baščaršija and Ferhadija generally have working wifi, and most cafés will share their network with paying customers. It’s a genuine alternative to a SIM if your stay is short or your itinerary keeps you in the city.

What’s the dialling code for Sarajevo?

Bosnia and Herzegovina’s country code is +387. Sarajevo’s local area code is 033, Mostar’s is 036, and Banja Luka’s is 051. You’ll need the full sequence — country code, area code, then the number — when calling a Sarajevo hotel, apartment host or driver from abroad.

Do I need to register my SIM separately from the foreigner registration at my accommodation?

Yes, they’re unrelated. The 24- to 48-hour registration with the foreigners’ service (often called the “bijeli karton” or prijava boravka) is about your stay in the country and is normally handled by your hotel or hostel. Registering a SIM card to your passport at the point of sale is a separate, one-off step required by the mobile operator, done once when you buy the card.
