Getting online in Republic of Korea
South Korea has some of the fastest and most complete coverage anywhere: on the subway, in tunnels, on the KTX high-speed train and on most hiking trails. In Korea this eSIM connects through SK Telecom, the country's largest network.
The one thing that trips visitors up: Google Maps has limited directions in Korea. Download Naver Map or KakaoMap before you arrive. They have English interfaces and give accurate walking and transit directions. KakaoT is the main taxi app, and Papago is often better than Google Translate for Korean.
Some Korean websites and apps ask for verification by SMS to a local number, which a data eSIM can't receive, so book anything that needs that before your trip. For a week in Seoul and Busan with plenty of navigation, 5–10 GB is usually enough.
