BOSTON, February 12 /PRNewswire/ -- OnePIN, Inc., the world's leading provider of social address book solutions, today announced that Vodafone is enabling their 16 million mobile subscribers in Turkey to extend their social networks with one-click on their mobile phones thanks to CallerXchange, OnePIN's contact exchange service. This peer-to-peer service, branded as Vodafone Kartvizit, allows users to easily connect and stay connected to friends, family and business associates - enhancing the value of mobile phonebooks.

With CallerXchange, Vodafone subscribers can conveniently choose to exchange contact information immediately after a phone call with one click. Subscribers are prompted to opt-in to the service at socially relevant times, which has driven significant usage. Since launch, subscribers have found value in sharing multiple points of contact beyond just their mobile number in order to stay connected with friends, family and colleagues.

Recipients of a CallerXchange message can easily click to add their friend's details directly into their phonebook. CallerXchange automatically ensures that information in subscribers' phonebooks is kept up to date, allowing subscribers to keep in touch with friends even if their information changes. With an enriched phonebook, Vodafone subscribers can use their mobile phone as a hub for social networking; resulting in increased communication via calls, SMS, emails and data services.

CallerXchange enables Vodafone subscribers to transform phone calls to friends into social connections; enabling people to stay connected to more friends and have more ways to connect to each friend, said OnePIN CEO and founder Feyzi Celik. We are very excited to see the strong uptake of the service in the market. After only a few months of commercial launch at Vodafone, CallerXchange has already connected over 2 million subscribers and is outperforming revenue expectations.

The CallerXchange service is a value-added service now available on all of Vodafone's new SIM cards that leverage Vodafone's new 3G network. The service is interoperable across handsets and networks and is compatible with any operator around the world.
