South Korea eSIM guide: local networks, airport SIM costs & setup

Why roaming and airport SIMs cost more in South Korea

South Korea is outside EU roaming, and navigation apps like Naver Map and KakaoMap plus Kakao T ride-hailing require live mobile data on the street.

At Incheon (ICN) and Gimpo (GMP), tourist SIM pickup counters require passport registration and charge around 20 € to 35 €.

With a prepaid South Korea eSIM from 5.49 € incl. VAT (custom & group plans — price negotiable), you receive the QR code and iPhone direct-install link right after payment.

4-step setup on iPhone and Android before you fly

Check that your phone is unlocked and supports eSIM by dialling *#06# — if an EID number appears on screen, your phone has an eSIM chip.

Install the profile over home Wi-Fi the day before departure. Keep the travel eSIM line switched off until you land, then enable it for Mobile Data with Data Roaming turned on for the travel eSIM (and Data Roaming turned off on your home SIM).
