Yes, you can install and configure your DataESIM for South Korea prior to your flight. This pre-installation process links the eSIM profile to your device. The data plan itself remains dormant, activating only upon detection of a supported network in South Korea. This design ensures that your data validity period commences precisely when you land and connect to a local carrier like KT or SK Telecom, providing instant internet access without delay or manual intervention post-arrival.
