CallerXchange is a person-to-person contact exchange service that connects people and enhances social networks. Mobile subscribers can easily connect and share information automatically by sending, inserting and updating content directly into their mobile phonebooks. Larger, more accurate phonebooks result in more calls, more SMS messages, and the use of more data services (e-mail, IM, Web) across all subscriber segments.

This unique value-added service increases subscriber stickiness and reduces churn.
