Logos Solvo’s TerraBook product is an innovative phone book service that enables the Mobile Network Operator’s subscribers to create and manage lists of contacts in a database kept by the MNO.  The TerraBook product is a solution to the limitations of the traditional SIM based phonebook and subscribers can now save and access an unlimited number of contacts from their mobile phones.



TerraBook allows subscribers to create a number of phonebooks on the TerraBook application server, and enables subscribers to access their phonebooks via their S@T enabled SIM card. Subscribers can create their own personal phonebooks, or create shared phonebooks for access by other subscribers.
