Wi-Fi
Wireless Internet is widely available in Seoul, which boasts nearly 10,000 free Wi-Fi hot spots. Public service centers and institutions such as transit centers, airports, libraries, hospitals, universities, and even many tourist spots offer free public access. Most hotels, stores, cafés, restaurants, and even taxis offer complimentary Wi-Fi access, although you may have to ask for the password or log in to their system.
Visitors can also pay for access from telecom companies such as KT, SK, and LG by logging in and paying by credit card at hot spots. Prepaid cards are also available for purchase at most convenience stores.
Visitors who need consistent access to Wi-Fi can also rent portable routers (often called “eggs” or “pocket Wi-Fi”) to create hot spots from major telecom providers such as KT and SK at Incheon and Gimpo International Airports. They can be reserved online in advance and picked up directly at the phone rental service desks of the telecom provider.
