Is this DataESIM plan valid for connectivity in adjacent non-EU territories, such as Belarus or Russia's Kaliningrad Oblast?

This DataESIM plan is strictly limited to countries within the European Union. Consequently, it will not provide service in non-EU territories such as Belarus or the Kaliningrad Oblast (Russia). Should your travels take you from Vilnius towards Minsk (Belarus) or into Kaliningrad, your DataESIM connection will cease at the EU border. Attempting to use a standard EU DataESIM plan in these regions will result in no service. For connectivity in such areas, a specific regional or global DataESIM plan that includes these countries would be required.
