Yes, you absolutely can install your WorldESIM for South Korea prior to your flight. We recommend doing this from the comfort of your home or at the airport while you still have Wi-Fi access. The eSIM will be installed on your device, but it will only become active and begin consuming data once you arrive in South Korea and connect to a local network, such as SK Telecom or KT. This ensures you're instantly connected upon landing in Incheon, ready to navigate or share your arrival.
