SK Telecom 5G and LG U+ 5G cover Gangnam, Hongdae, Itaewon and the central corridor of Seoul with reliable data for the subway, KakaoPay payments and Naver Map walks through Bukchon and Insadong. Signal holds along the entire Gangnam Station outdoor plaza and inside the modern COEX Mall convention complex, drops inside the older stone halls of Gyeongbokgung Palace where the heavy tile roofs and the granite walls block reception, and weakens in the steep residential alleys of Bukchon Hanok Village where the narrow lanes and the old hanok houses limit the line of sight to the nearest tower.

Yes. Use your physical SIM for calls/SMS and the eSIM for mobile data. Disable roaming on your physical SIM.

Yes. eSIM offers instant activation without visiting a store. Coverage matches physical SIMs in covered areas.
Yes. 5G works around the Gyeongbokgung Palace complex and the nearby Gwanghwamun Square for navigation and photos, but expect signal drops inside the heavier stone halls where the ancient tile roofs and granite walls block reception. We recommend downloading offline maps of the palace grounds because the deeper inner courtyards have thin coverage. Your eSIM is useful for KakaoPay payments at convenience stores, navigating with Naver Map (Google Maps is less accurate in Seoul), and renting hanbok costumes through the local apps. Note that the T-money transit card requires a separate physical card from the station vending machines; your eSIM keeps the data running while you tap the card on the subway gates.
