Is this SouthESIM for Denmark valid for the Faroe Islands or Greenland?

This is a really important distinction for your travel planning, and the answer is no. While the Faroe Islands and Greenland are part of the Kingdom of Denmark, they are geographically and administratively distinct and are not part of the European Union. Therefore, our SouthESIM plan specifically for Denmark will not provide coverage in these territories. Attempting to use it there would likely result in extremely high roaming charges from your home carrier, or simply no service. For these unique destinations, we recommend looking into specific local options or global eSIM plans if available.
