Mobile internet in Bosnia and Herzegovina: eSIM, roaming or local SIM?

Updated October 30, 2026

Bosnia and Herzegovina is not in the EU, so EU roaming rules do not apply. Sarajevo and Mostar are often part of a Balkan round trip.

The networks

Our Bosnia and Herzegovina eSIM connects to HT Eronet (4G). The internet exit is in Europe (United Kingdom). That is a short route compared to roaming via Asia, but a little slower to respond than a fully local connection; for maps, messaging and video it makes no practical difference.

Roaming, local SIM or eSIM?

• Roaming with your home plan: easy, but often expensive, and the data usually runs through your home country.
• Local SIM card: cheap, but you need to find a shop after arrival, often show your passport, and swap the SIM in your phone.
• eSIM: bought before the trip, QR code by email. Your home SIM stays in the phone, so your number stays reachable for calls and SMS.

How much data do you need?

Our plans run for 30 days with 5 GB, 10 GB or 20 GB for the whole period. 5 GB covers maps, rides and messaging on a short trip, 10 GB is the most popular choice, 20 GB is for long trips, lots of video or working on the road.

The eSIM uses one network (HT Eronet). In remote mountain areas coverage can be weaker, so download offline maps before hikes.

Install at home, the plan starts on arrival

You can install the eSIM before your trip on your Wi-Fi at home. The plan starts once the eSIM connects to a local network. After arrival, switch mobile data to the eSIM and turn on data roaming.

• Data only, no local phone number. Call and text via WhatsApp or similar apps.
• Does your phone support eSIM? eSIM check.
• Step-by-step for iPhone and Android: installation guide.
• The QR code works only once, so do not delete the eSIM during your trip.
