It was just a month ago that North Korea started allowing mobile internet access to visitors (while still restricting it from citizens), but now a tour group says that program has ended. First reported by North Korea Tech, a post on the Koryo Group site indicates that tourists can still purchase SIM cards for international calling, but internet access is not available, a return to its policy from January. A recent blog post from the 22nd goes into more detail, explaining that 3G Koryolink access for foreigners "has been restricted to long term visitors/residents of Pyongyang only." With no word from the government on the policy change you'll have to insert your own reasoning, although we imagine Eric Schmidt is not pleased.
