Electricity and Voltage

The standard voltage in Korea is 220 volts at 60 Hertz, and the outlet has two round holes. If you do not have a multi-voltage travel adapter, you may ask to borrow or purchase one from your hotel's front desk. You can also find them at the airport, retail stores, major duty-free shops, and even convenience stores.

Mobile Phone Rentals and Roaming Service

Korea's major airports, including Incheon, Gimpo, Gimhae and Jeju International Airports, have roaming centers, operated by local network service providers. Visitors can get their mobile devices connected for roaming here after a simple registration process. In addition to roaming services, SIM Card purchase, Wi-Fi egg rentals and even smart phone rentals are available. More information about the fees, location of roaming centers and other details can be found on the service provider's official website.

SIM Card Purchase (Korea SIM card)

Travelers can purchase a SIM card to insert into their personal cell phone device to enjoy unlimited data or receive a personal number while traveling in Korea. These prepaid SIM cards usually cost less than roaming services and offer unlimited data for a period of 5, 10 or 30 days. The SIM cards can be purchased at CU convenience stores at Incheon International Airport, 7-Eleven stores in Seoul, Busan, Jeju and other major cities and Korea SIM Card’s official website. For convenience, travelers are recommended to make a purchase in advance online or at the airport.

Internet

In Korea, the Internet is easily accessible through the free public Wi-Fi service available in most public locations such as airports, subways stations, train stations, and certain bus stops. PC rooms and coffee shops are also great places to go. PC rooms are mostly open 24 hours.

Postal System

Tourists may naturally want to send postcards or letters to their friends and family back home. A few years ago, mailboxes could easily be found on almost every other street and in buildings. These days, mailboxes are rarely seen on the streets since online communication has become the norm. If you cannot find a mailbox, you can ask your hotel front desk to put your letters or postcards in the mail or you can visit a nearby post office. Visit Korea Post for more details on post office locations and service fees.

Public Phones

As the use of cell phones, smartphones and mobile devices has become widespread in Korea, the number of public phone booths has steadily decreased. However, public phone booths can still be found at a few heavily trafficked areas. Korean public phones generally provide local and international call services alike and accept payment by cash or phone cards. Payment can also be made with a transportation card or a credit card, but this option is not accepted at all phone booths so please check in advance.
