The application is a management and dialer for convenience of subscribers. It allows to make calls and send messages via both numbers without requiring any GPRS or WIFI connectivity. While advanced features like managing blocked numbers, suspending service or missed call notifications requires Internet connectivity via GPRS or WIFI.
