Mobile telephony and communication with North Korea

As readers of this blog will be well aware, mobile telephony has gradually been spreading in North Korea, mainly through the efforts of Orascom, but also, according to many anecdotal reports, use of Chinese mobile services whose signals reach into North Korea along its border with China.  The Telegraph has published an article that provides some interesting, current detail on how clandestine mobile phone calls are being used by North Koreans who have fled to the South, to communicate with their relatives and others inside North Korea.  Entitled "What North Koreans really think of Kim Jong-Un," it is well worth reading.
