This specific WestESIM plan is precisely tailored for use within Serbia only. While planning a comprehensive Balkan tour, it's crucial to understand that your WestESIM connectivity will cease if you cross into neighboring countries such as Croatia, Bosnia and Herzegovina, or Montenegro. For seamless data access across multiple destinations, we recommend exploring our comprehensive European plans or purchasing individual eSIMs for each country on your itinerary, ensuring uninterrupted service whether you are in Belgrade or Sarajevo.
