Koryolink (Korean: 고려링크, styled as koryolink), a joint venture between Egyptian company Global Telecom Holding and the state-owned Korea Post and Telecommunications Corporation (KPTC), is North Korea's only 3G mobile operator. The Egyptian company owns 75% of Koryolink, and is known to invest in infrastructure for mobile technology in developing countries. It covers Pyongyang, and five additional cities and eight highways and railways. Phone numbers on the network are prefixed with +850 (0)192. Despite being a 3G network, there is no Internet access for domestic users although as of April 2014, mobile internet access for foreigners with limited speed or traffic amount is available at a comparably high price 
Orascom Telecom Holding was awarded the licence to establish a 3G mobile network in DPRK in January 2008. Koryolink has deployed its 3G network to initially cover Pyongyang, which has a population of more than 2 million, with an ambitious plan to expand its coverage to the entire country.
At network launch in December 2008, the network had 5,300 subscribers. Orascom reported 432,000 North Korean subscribers after two years of operation (December 2010), increasing to 809,000 by September 2011, and exceeding one million by February 2012. By April 2013 subscriber numbers neared two million.
