This specific CoreESIM plan is geo-restricted to South Korea only. It is not provisioned for multi-country roaming across other East Asian nations. If your itinerary includes travel from Seoul (ICN) to destinations such as Tokyo (NRT) in Japan or Taipei (TPE) in Taiwan, your data connectivity from this eSIM will terminate upon exiting the South Korean network. For seamless connectivity across multiple countries in the region, CoreESIM offers distinct regional or global eSIM profiles designed for broader geographical coverage.
