The app helps you with the sometimes cumbersome procedures of setting up a convenient call diversion. For example, there is the option of setting up different numbers for 'immediately' or 'busy' or 'no network'.
In addition, the call forwarding can be time-controlled, so that the phone rings for a defined period of time and then diverts. This also allows the ringing time for the voicemail box to be adjusted.
In addition, the SIM PIN can be changed using the PUK, the prepaid credit can be queried or topped up, or the call waiting function can be changed.
