Travelling in South Korea means moving between Seoul, Busan, Jeju and the DMZ. Our eSIM keeps you connected across all of it, from landing to departure.
Network coverage in South Korea
Coverage in South Korea comes from SKTelecom and LG U+, giving you 5G where it is deployed and 4G everywhere else. South Korea has among the fastest and most complete 5G networks in the world, including in subways and on the KTX. Coverage reaches the summit of Hallasan on Jeju and every subway line in Seoul.
How much data do you need?
As a rule of thumb, 500 MB to 1 GB a day covers maps, WhatsApp, ride-hailing and social feeds. A week of city sightseeing usually fits in 5 GB; a road trip with constant navigation is better served by an unlimited plan.
