Is this CoreESIM plan applicable to other Baltic states like Latvia and Estonia?

The specific CoreESIM plan you are viewing is provisioned for use exclusively within Lithuania. While Latvia and Estonia are geographically adjacent and part of the EU, cross-border functionality is dependent on the plan's defined roaming agreements. If your itinerary includes travel to Riga or Tallinn, a regional CoreESIM plan covering multiple EU countries would be required to maintain continuous data service without incurring out-of-plan charges. Always verify the precise country coverage listed for each CoreESIM product.
