Electricity and Voltage
The standard voltage in Korea is 220 volts (and 60 Hertz, or cycles), and the outlet has two round holes. If you do not have a multi-voltage travel adapter, you can borrow one from your hotel's front desk for free of charge (however, some establishment may request a minimal fee as deposit, covering for possible loss). If you would like to purchase one in Korea, you can find them at the airport, any of the retail stores, major duty-free shops, convenience stores or even stationery stores.
As the distribution of cell phones, smart phones and related mobile gears increases in Korea, public phone booths are rarely seen on streets and public facilities today. However, there are still some public phone booths at popular sites, bus stops, and subway stations. Korean public phones generally provide local and international call services alike with payment by coins or phone cards.
Telephone cards can usually be purchased at convenience stands or stores near the telephone booths, and the remaining balance cannot be exchanged for cash. Most of these cards are valid for a period up to three years; however, some may have different validity period so make sure to double check the information before making a purchase.

Internet service is often provided in public places such as airports, train stations, and bus terminals in Korea. PC rooms and internet cafes are also great places to go for and they are mostly 24 hours in operation. In addition, many of popular tourist sites are equipped with free Wi-Fi connections as well help international visitors to stay connected with friends and families back at home.
Any visitor to a foreign country may naturally want to send postcards or letters, sometimes parcels to home country. A few years ago, mailboxes can be easily found on almost every other street and in buildings. Finding a mailbox today is a bit more difficult because of the Internet revolution. 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 go directly to a nearby post office. Visit Korea Post for more details on post office locations, parcel services, purchasable items (stamps, postcards and letters for souvenirs) and more.
