Is this DataESIM plan valid for non-EU Balkan nations such as Turkey, Serbia, or North Macedonia?

This specific DataESIM plan is precisely geo-fenced for use exclusively within Bulgaria and the broader EU zone. It is crucial for travelers to understand its operational boundaries. Should you transit from Sofia into a non-EU country like Turkey (e.g., Istanbul), Serbia (e.g., Belgrade), or North Macedonia (e.g., Skopje), this particular DataESIM plan will cease to provide connectivity. For multi-country itineraries spanning EU and non-EU regions, consider a dedicated regional plan or a separate eSIM for each distinct geographical zone.
