Does this CoreESIM Guinea plan extend its data coverage to adjacent West African nations?

CoreESIM's Guinea data plans are specifically provisioned for network access within Guinea's national boundaries. Cross-border roaming into adjacent territories such as Senegal (e.g., Koundara region), Sierra Leone (e.g., Pamelap), or Ivory Coast will result in a loss of connectivity as the device attempts to register on unauthorized foreign networks. For multi-country itineraries, CoreESIM recommends a dedicated regional eSIM or individual country-specific plans to ensure continuous service.
