Gimpo Airport Wi-Fi can cover immediate arrival tasks, but mobile data is more useful once you continue by subway, bus or taxi.
Your options are airport Wi-Fi, a travel eSIM, Korean prepaid SIM or home roaming.
NoveSIM plans are data-only and do not provide a Korean number, conventional calls or SMS.
Quick answer: Use the airport’s official Wi-Fi inside the terminal and prepare a South Korea eSIM before departure for maps and messages during the journey into Seoul.
