South Korea eSIM travel guide

We compared 217 eSIM plans for South Korea from Airalo, Holafly, Saily, Nomad, Maya, Yesim, Roamless, Virgin Connect Roam, Roam2Go, Breeze, MobiMatter, shibaSIM, Simbye, The SIM Shop.

South Korea has some of the fastest mobile internet in the world, and daily life there runs on apps. Navigation, taxis, food delivery and many bookings work best through Korean apps, so reliable data matters from the moment you land.

Networks and coverage

Korea's networks are SK Telecom, KT and LG U+. All three have excellent 4G and 5G coverage in cities, on the subway and on the KTX high-speed trains, and good coverage in most of the countryside and on Jeju Island.

Maps and taxis

Google Maps does not give full walking or driving directions in South Korea. Most visitors use Naver Map or KakaoMap instead, and Kakao T for taxis. All of them need mobile data.

How much data you need

Korean apps and fast networks make it easy to use a lot of data. For a week, 5 to 10 GB is usually enough. Choose unlimited if you stream, make video calls or upload a lot.

Fixed data or unlimited?

Fixed data plans are the cheapest choice for maps, messaging and browsing. If you use more than about 1.5 GB a day, compare the unlimited passes above.
