Prepaid international card services

Prepaid calling card service can be used to offer cheap calls from mobile phones in a specific market. To give an example: Castor has just launched its prepaid card service in Guinea where it offers cheap calls from mobile phones based on interconnection with all key mobile operators in the country. This concept is also being rolled out in other African countries.
