Using mobile data in South Korea

Your eSIM connects to a local network in South Korea, so maps, messages, rides, and translation work like they do at home. Data roaming must be switched on for the eSIM line. That is normal for travel eSIMs and it does not cost extra.

Networks in most of Asia are fast and data is cheap by global standards. An eSIM saves you the airport SIM counter line after a long flight.

Mobile networks in South Korea

eSIM plans for South Korea connect through SK. 5G is available where the network has built it out. Elsewhere you get 4G.

SK Telecom is the country's biggest operator and it runs a leading 5G network. Korea is one of the most wired places on earth, so data is fast and reaches nearly everywhere, from Seoul to the mountain trails and the subway tunnels.

A fully connected country

Signal follows you across the country, in the cities, on the KTX trains, and even underground on the metro.

Only the remotest mountain peaks and outer islands see any drop.

Apps and plan choice

KakaoTalk is the messaging app everyone uses, and its map and taxi services are handy. Some services ask for a local number, which a data-only eSIM does not provide, so lean on the international options where offered.

A short unlimited plan fits a city break. A mid-size monthly plan covers a longer trip.

Good to know
