Is this WestESIM plan valid for non-EU neighbors like Serbia or Moldova?

The WestESIM plan for Romania (and the broader EU) provides premium connectivity exclusively within these regions. If your travels extend to non-EU neighboring countries such as Serbia (e.g., Belgrade) or Moldova (e.g., Chisinau), your WestESIM connection will cease at the border. These nations are outside the EU roaming agreements. For seamless cross-border connectivity, we recommend exploring WestESIM's multi-country European plans, which are designed to cover a wider range of destinations including non-EU countries.
