Light
1–3 GB
Maps, messaging, the occasional email. Great for short trips.
Standard
5–10 GB

Network coverage & good to know
In South Korea your eSIM automatically connects to the strongest available partner network — typically 4G/LTE or 5G in cities and tourist areas. Coverage can vary in very remote regions. After installing, enable data roaming for the eSIM profile (this is normal and incurs no extra cost — you're using your booked plan). Tip: install the eSIM over Wi-Fi before departure so you're online the moment you land.
Good to know: Google Maps navigation is limited in South Korea — use Naver Map or Kakao Map instead, which makes reliable data essential. The network is superb nationwide, even on the subway.
