Our specific EastESIM plan for Serbia is tailored exclusively for use within Serbia's borders. If your journey takes you beyond, for instance, from Belgrade to Sarajevo (Bosnia), Kotor (Montenegro), or Zagreb (Croatia), your connection will cease at the border. For multi-country Balkan adventures, EastESIM offers convenient regional plans that cover several destinations, ensuring seamless connectivity across your entire itinerary without needing multiple eSIMs.
