Telecommunications/Postal Service


As an IT powerhouse, Korea provides high-speed internet services to people at anytime, anywhere. Major Internet service providers are “KT olleh, SK broadband, and LG Uplus.” Application for service can be made by phone or at the service provider’s website. Internet service expenses include subscription fee, basic rate, and equipment (modem) rental fee. In general, contracts are entered into for a term of one, two, and three years, thus granting partial discount of the rates, but termination during the agreed-to term can result in penalties.

※ Use of combined service—combining various telecom services (e.g., Internet, phone, mobile telecom) and selling them—can give the benefit of discount rates.
