iZone Telecom provides Defne’s Missed Call Notice Service which provides “who called when called” information to subscriber while s/he is out of reach by phone. Out of reach cases occur due to being out of network coverage or the phone being switched off.


As soon as subscriber becomes available (attached to network), information which includes phone number, time and number of call attempts per each caller during his/her absence is prepared and sent as SMS. It is observed that 25% of subscribers call back after receiving missed call information. On the other hand, meantime, an availability notification about called party’s status is sent to calling parties as a feature.
