While Seoul offers widespread public Wi-Fi, especially in major areas and subways, it can be inconsistent, slow, or require registration. For reliable, secure, and always-on connectivity while exploring Gyeongbokgung Palace or using maps, an eSIM from Cellesim is highly recommended. It saves time and ensures seamless communication.
