This specific WestESIM plan is designed for use exclusively within Bulgaria and the broader EU region. It is crucial for travelers planning to explore the Balkans to understand that countries like Turkey, Serbia, or North Macedonia are outside the EU roaming zone. If your journey takes you from Sofia to destinations such as Istanbul, Belgrade, or Skopje, your WestESIM plan for Bulgaria will not provide coverage in those non-EU territories. For multi-country trips, consider our regional Europe eSIM options.
