Tele2 launched the +46 VoIP applications to enable its Swedish customers to make and receive calls while travelling without incurring roaming charges, for the price of a normal mobile voice call. Their challenges are to stay relevant and grow revenue from innovative mobile value-added services and customers' reluctance to use mobile phones when abroad to avoid heavy roaming charges. They chose Cisco to overcome these challenges. They have implemented Tele2's +46 VoIP app lets Swedish users call home cheaply, over Wi-Fi, from anywhere in world. The result of implementing Cisco was improvement in customer loyalty with long-term revenue benefits.
