The easiest and quickest way to traverse the crowded city is on the subway, which serves all the main areas of interest. Station signs are written in English as well as Korean, and most lines have English announcements too. Subways are extremely crowded during the morning and evening rush hours, but are generally safe, though plagued with hawkers and beggars. Tickets are bought from vending machines or at ticket windows. Buses are frequent and cover the whole city, but tend to be very crowded. Tickets can be bought on boarding, or debit tickets can be purchased. Taxis are readily available. Regular taxis (white or silver) charge an initial fee and have a complex system of metering thereafter. Black luxury taxis, called Mobeom taxis, are superior both in condition and service.
Electric current is 110 or 220 volts, 60Hz. Most hotels operate with 220 volts. Two-pin round plugs are standard.
The official currency is the South Korean Won (KRW). Currency can be exchanged at most banks and at casinos. Most merchants in the cities accept major credit cards, but Koreans traditionally prefer cash. ATMs at banks are usually accessible only during banking hours, and instructions on the machines are generally only in Korean. Most public ATMs at convenience stores and subway stations are available 24 hours. US$ are accepted in a limited number of major locations and hotels.
The international dialling code for South Korea is +82. Telecommunications are well developed and internet cafes are widely available. Although mobile telephones are widely used by locals, there is no GSM network and some foreign phones will not work in South Korea, even when on international roaming. It's possible to hire a local mobile phone.
