This report submitted to the European Commission buy TERA Consultants examines tariffs for charging for mobile telephone calls in the European Union. In North American, the cell phone owner pays to make or to receive calls. In Europe, the caller pays a special (higher) charge to call a cell phone. (Call from the U.S. to a European cell phone cost up to 10 times more than terminating on a landline.) This report examines alternative charging schemes and the effect on customer rates and industry competition. The two schemes are called CPNP (Calling Party Network Pays) and BAK (Bill And Keep – shared costs).
