Is it true that there are no mobile phones in North Korea? I have heard opposing views saying that there is a working mobile network that many people use and views that say there isn't any of them in the whole country.
More clarification of international calls from North-Korea is given here, dated March 27, 2013.
“3G access is no longer available for tourists to the DPRK. Sim cards can still be purchased to make international calls but no internet access is available,” the Beijing-based North Korean tourism specialist said in a short notice on its website.
According to a recent BBC article
At the start of 2012 Koryolink claimed to have one million 3G subscribers.
Koryolink being North Koreas only 3G operator.
According to the same BBC article:
The service can only be used to make voice calls, and all international calls are banned.
However tourists and visitors can use mobile data.
This blog post from Google's Eric Schmidt also supports the view that while North Korea's mobile infrastructure is extremely limited, it does exist.
It seems clear from the wikipedia page that there are plenty of mobile phones. The issue of being able to make international calls is a different matter, but my original question seems answered.
