Using an eSIM in South Korea
South Korea's main networks are SK Telecom, KT and LG U+, and Seoul, Busan and the intercity corridors have very dense mobile coverage, including on the subway.
Many visitors use Naver Map or KakaoMap for walking and driving directions because that is what locals use, and both work best with a live data connection.
Good to know
- Install Naver Map or KakaoMap and Papago (a Korean translation app) before arriving, and check that your usual map app does what you need.
- KakaoTalk is the standard chat app; many restaurants, taxis and shops use it.
- Jeju Island and mountain areas such as Seoraksan can have gaps outside towns and trailheads.
South Korea eSIM questions
- Do I need a Korean phone number for apps like KakaoTalk or Coupang?
- Sign-up often asks for a local number, and some services accept a foreign one with verification. Create accounts with your home number before you fly, and use a data eSIM for connectivity.
- Which map app should I rely on in South Korea?
- Naver Map and KakaoMap are what locals use for directions and transit, so many visitors install one of them alongside their usual app. Both need data, so an eSIM keeps them working on the move.
- Will it work on the subway in Seoul?
- Seoul's subway has broad mobile coverage across the main networks, so maps and chat apps generally keep working underground.
