Is this CoreESIM plan valid for non-EU countries bordering Romania like Serbia or Moldova?

This CoreESIM data plan is specifically configured for use within Romania and the broader European Union. It is imperative for travelers to note that non-EU neighboring countries, such as Serbia (e.g., Belgrade), Moldova (e.g., Chisinau), or Ukraine, are not covered. Crossing into these territories will result in a loss of service. For itineraries including these nations, CoreESIM advises selecting a multi-country European plan that explicitly includes these non-EU destinations.
