Operators generate two revenue streams:

  • Premium VAS revenue with each message;
  • Increase in voice and data revenue as subscribers add more contacts to their phonebook (Primary SIM usage for pre-paid).

Subscribers pay an out-of-bundle, premium SMS price (typically ~1.3-times the value of an SMS) to send their business card.

  • The phonebook is one of the most universally used application on the phone.
  • There are many contact exchange applications available in App Stores; however, none are interoperable across all handsets and networks; none are automatically available after ending a call with a new friend; and none create direct revenue for mobile operators
