Absolutely. A key advantage of CoreESIM is the capability to pre-activate your profile before your arrival at Incheon International Airport (ICN) or Gimpo International Airport (GMP). Upon purchase, a QR code is sent to your email for installation. Perform this step while you have a stable internet connection prior to your flight. This ensures that your device's eSIM line is configured and ready to connect to local Korean networks immediately upon deplaning, providing instant data access.
