Power & Connectivity (SIM)

Bosnia and Herzegovina uses 230V / 50Hz with Type C and Type F sockets (European two round pins). Bring a Type C/F adapter; travellers from 100–120V countries need a converter for devices that are not dual-voltage.

The main operators are BH Telecom, m:tel (mtel) and HT Eronet, with good 4G in cities and towns. Prepaid SIMs are easy to buy at operator shops, kiosks and supermarkets; bring your passport, as registration is required. There is no EU-style free roaming, so a local SIM or eSIM is often the cheapest option.

eSIM travel plans (such as Airalo) are a convenient option: buy one online before arrival and install it in minutes, with no physical SIM or shop visit. This avoids passport registration and is handy since Bosnia and Herzegovina is outside EU free roaming.

Free Wi-Fi is widely available in cafés, hotels and restaurants in Sarajevo, Mostar and other cities. Coverage and speeds can be weaker in rural and mountain areas, so a local SIM or eSIM helps when on the move. Use a VPN on public networks for sensitive tasks like banking.

Bosnia and Herzegovina has an open internet with no significant restrictions. All standard apps and services — messaging, social media, maps and streaming — work normally.

Handy apps include Google Maps and Maps.me (offline maps are useful in the mountains), plus local phone-dispatch taxi services such as Sarajevo Taxi and Crveni Taxi (Sarajevo). Ride-hailing apps like Uber and Bolt are very limited or absent, so calling a taxi is the norm.

Bosnia and Herzegovina's country code is +387. App-based calls (WhatsApp, Viber, FaceTime and similar) are common and popular. Save numbers in full +387 format so they work from any network, and note there is no EU-style free roaming for calls.
