Koryolink
Koryolink is the commercial brand of a 3G mobile telecommunications network in North Korea, launched in December 2008 as North Korea's first nationwide cellular service provider.[1][2] It operates through Cheo Technology, a joint venture in which Egypt's Orascom Investment Holding holds a 75 percent stake and the North Korean state-owned Korea Posts and Telecommunications Corporation holds 25 percent.[1][2] The network achieved rapid subscriber growth, reaching 91,000 users within its first year, over 400,000 by the second year, and nearly one million by 2011, with estimates of around three million subscribers served under its operations.[1][2] Coverage extends to Pyongyang, major cities, key roads, and much of the country, facilitating domestic voice calls, SMS, and limited data services for approved handsets that block unauthorized applications and enable random content monitoring.[1] A parallel state-controlled network, Kangsong, emerged around 2013, but Koryolink remains a dominant provider amid overall mobile penetration estimated at 40 to 50 percent of the population as of 2023.[1][3] From inception, Koryolink incorporated advanced surveillance infrastructure, including a Legal Interception Gateway capable of monitoring up to 2,500 targets simultaneously for voice, text, and data traffic, with storage for intercepted communications, reflecting its design to prioritize regime oversight over unrestricted connectivity.[1][4] Separate encrypted networks exist for high-ranking officials, and international roaming or internet access is segregated from domestic services to prevent cross-contamination.[1][4] Orascom faced challenges repatriating profits due to North Korean restrictions and international sanctions, leading to a loss of operational control by 2015, though a United Nations exemption permitted continued infrastructure maintenance.[2][5]
