Install a South Korea eSIM before departure while reliable Wi-Fi and the order details are available.
Installation adds the profile; activation and first network connection may happen later under the selected plan’s rules.
NoveSIM plans are data-only and do not include a Korean number, calls or SMS.
Quick answer: Confirm the phone is compatible and unlocked, scan the QR code once, label the line South Korea, and keep it off until the plan instructions say to connect.
