KnowRoaming does not provide unlimited data eSIM plans for the Balkans. Travelers who need ongoing data access can choose from a range of fixed‑data options that cover Albania, Bosnia and Herzegovina, Bulgaria, Croatia, Kosovo, Montenegro, North Macedonia, Serbia, and many other countries in the region. Example plans include 100GB valid for 180 days, 50GB valid for 60 days, and 20GB valid for 30 days. These plans offer substantial data allowances and are tailored to the Balkans while also covering a wide network of neighboring destinations.
Selecting a fixed data plan can be more economical unless a traveler anticipates extremely heavy data usage; in that case the fixed‑data model will still provide a clear threshold and predictable cost compared to an unlimited offer, which is not available from KnowRoaming for this area.
