Payphones can be found at the airport, subway stations, and major tourist attractions. In Korea, you'll find phones that accept coins, prepaid cards, and credit cards, as well as phones that only accept coins and phones that only accept cards. To use the phones that accept cards, you must purchase a prepaid phone card from a convenience store (cards come in 3,000; 5,000; and 10,000 won increments), use a T-Money card or credit card, or dial collect.




Coin phones accept 10, 50, and 100 won coins, while phones that take cards accept prepaid cards, T-Money cards, and credit cards. Visitors should be aware that payphones can be difficult to find in some areas, since most Koreans rely on mobile or smartphones.


Using Payphones


If you're using a phone that takes cards, first pick up the receiver and then insert your card. The remaining balance will be displayed. Enter the phone number you wish to dial. To use a T-Money card, hold the card up to the card reader. The phone will make a sound when your card has been read, after which you can dial the number you wish to call. For coin phones, deposit the required amount and then dial the number.
Local calls are 70 won for every 180 seconds. Calls placed to a mobile phone cost 70 won for every 38 seconds.




Internet Access


Internet access is widely available throughout Seoul. Airports, hotels, tourist information centers, public facilities such as subway and railway stations, and many restaurants and cafés have Wi-Fi, LAN Internet access, or both. You can even connect to the Internet on KTX trains. You can also go to an Internet café, called a "PC bang” (“PC room"), which are found in most commercial and residential areas of the city. They cost about 1,000 to 2,000 won an hour.




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 (“bimil beonho”) 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, and cost approximately 1,000 won per hour or 3,000 won per day.
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. Other rental agencies can be found in major tourist spots such as Seoul Station, Insa-dong, and Myeong-dong. A portable router usually costs between 5,000 and 10,000 won per day to rent.
