"Telecommunications Business Act" of Korea prohibits the marketing and the sales of paid telecommunications services by companies that are not registered and authorized to conduct telecommunications business in Korea. Being a global Internet operator, Skype does not have such authorization from the Korean government and therefore cannot offer its telecommunications services directly to the users in the Korean territory.
"Telecommunications Business Act" applies not only to the Korean nationals but also to anyone residing in the territory of Korea, including temporary visitors. That is why Skype has teamed up with Daesung to provide its VoIP services in Korea.

We are sorry for the inconvenience caused to you.
