Above all else, North Korea is defined by its secrecy – this isolated nation tightly controls the flow of information into and out of its borders, and this is never more apparent than with its telecoms sector. In 2008, Egypt’s Orascom Group partnered with the state-owned Korea Post and Telecommunications Corporation (KPTC) to launch mobile provider Koryolink, but beyond this, so little information is disclosed regarding communications in North Korea that much of what we know is guesswork pieced together by organisations dedicated to this mission.
