Phone cards are used to call virtually every country in the world.  Interestingly enough, Russia is at the top of the list of the most popular international calling destinations.

Russia Cards keeps a track of which countries are called the most using our phone cards.  The list of the most popular destinations found below is updated weekly.  The US is by far the most often called country.  Since Russia Cards is a U.S. based site, for our purposes we consider calls to countries outside the United States as international.  Russia consistently is on top of the list of the most called international destinations.
