To use the phones that accept cards, you must purchase a prepaid phone card from a convenience store, use a T-Money card or credit card, or dial collect.

Cards come in increments of KRW 3,000, KRW 5,000, and KRW 10,000.

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 KRW 70 for every 180 seconds. Calls placed to a mobile phone cost 70 won for every 38 seconds.

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,” or PC room, which are found in most commercial and residential areas of the city. They cost about KRW 1-2,000/hour.

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.
