Korea has excellent internet infrastructure, and visitors can find Wi-Fi in airports, hotels, cafes, malls, stations, and public areas. But public Wi-Fi still needs normal privacy caution. Use it for maps and browsing, but be careful with banking, passwords, sensitive work, and unknown networks.
This guide explains how visitors can use Wi-Fi safely in Korea.
