SK Telecom 5G and LG U+ 5G cover Haeundae, Seomyeon, Nampo and the coastal corridor of Busan with reliable data for the Busan Metro, KakaoPay payments at Jagalchi Market and Naver Map walks through Gamcheon Village. Signal holds along the entire Haeundae Beach promenade and inside the modern Shinsegae Centum City department store, drops inside the older metal-roofed stalls of the Jagalchi seafood market where the humidity and the metal roofing block reception, and weakens on the ferry crossings to Geoje Island where the open water and the distance to the coast reduce the line of sight to the nearest tower.

Yes. 5G works along the Haeundae Beach promenade and the Busan Aquarium for navigation and photos, but expect drops if you go paddleboarding or kayaking off the coast because the open water and the distance to the tower reduce coverage. We recommend downloading Naver Maps offline before heading to the beach because Google Maps is less accurate in Busan. Your eSIM is useful for KakaoPay payments at the Jagalchi seafood market, navigating the Busan Metro with Naver, and translating menus with Papago at Korean BBQ restaurants. 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.
