“I used the Horizon Balkans eSIM on a recent trip. The best part was not having to think about buying a new SIM every time I crossed a border. I used it for maps, WhatsApp, checking hotels, finding restaurants, and looking up beaches and places to visit. The package covers Albania, Bosnia and Herzegovina, Bulgaria, Croatia, Greece, Montenegro, North Macedonia, and Serbia and I added Kosovo eSIM to the same order. I would use it again for another trip through the Balkans”
A Bosnia and Herzegovina eSIM is a prepaid mobile-data plan for your trip. Install it on a compatible, carrier-unlocked phone before departure, then select it as your data line within the plan's coverage area.
Arriving at Sarajevo International Airport? Walk out already online rather than searching for a SIM counter. Your Bosnia and Herzegovina eSIM activates as soon as you land, so you can order a ride into the valley, open your map of the old town, and tell people you've arrived before your bag appears. From Sarajevo's minarets and church spires to the famous bridge at Mostar, your data keeps up across the country's main cities and travel areas.

Choose a data plan for Bosnia and Herzegovina, install the eSIM over reliable Wi-Fi before your trip, and follow the selected plan’s activation instructions. Your regular SIM can stay in your phone, while the eSIM gives you mobile data for travel apps, messaging, maps and browsing.
Pick a destination, data allowance and validity period.
Scan the QR or auto-install in the app — no physical SIM.

Pick the profile closest to your trip. The estimate assumes normal use — maps, messaging, photos, a short call home.
As a rule of thumb, a 3–4 day city break runs on about 1–3 GB, a one-week trip on 3–5 GB, a two-week multi-country tour on 8–12 GB, and working on the road takes about 1 GB a day, so 15 GB or more for two weeks.
In total, a 1 GB data allowance covers roughly 330 shared photos, 17 hours of social media and browsing, 2.9 hours of video calls, 13 hours of music streaming, or about 200 hours of maps and navigation. Messaging apps barely use data.
Sarajevo · City guide
Sarajevo layers Ottoman bazaars, Austro-Hungarian boulevards, and recent history into one walkable valley, and a Sarajevo eSIM helps you read every layer. Find your way through the copper-smiths' alleys of Bascarsija, look up the story behind the Latin Bridge as you cross it, and grab a tram or taxi when the hills get steep. With data on, hopping between a cevapi grill and a hilltop viewpoint stays simple.
Sarajevo eSIM — set up before you fly →Mostar · City guide
Mostar revolves around its rebuilt Ottoman bridge, and the crowds around it can be intense. A data plan for Mostar lets you time your visit to Stari Most, navigate the cobbled bazaar streets, and check transport for day trips out to Blagaj or the Kravica waterfalls. Mobile data also helps you book a guide or read up on the city's layered past while you stand right in the middle of it.
Mostar eSIM — set up before you fly →Banja Luka · City guide
Banja Luka, the relaxed riverside hub of the country's north, is an easy place to settle into once you can stay connected in Banja Luka.

With data running, this green, café-friendly city is straightforward to explore at your own pace.
Banja Luka eSIM — set up before you fly →Tuzla · City guide
Tuzla surprises visitors with its salt-lake beaches right in the heart of town. A Tuzla eSIM helps you find the Pannonian Lakes, check event listings in the lively main square, and arrange transport across this industrial-turned-leisure city in the northeast. Whether you're swimming in a salt lake or planning your next stop, mobile data keeps Tuzla easy to get around.

Bosnia sits outside the EU, so the allowance on your contract stops at the border — and here the border is usually a road, not an arrivals hall. The network the plans name, and how to size one.
The old bridge at Mostar, Sarajevo's bazaar and the drive through the hills — here's how to plan mobile data for Bosnia, where EU roaming stops.
