Missed Call Service directs your callers to a short announcement that tells them they can leave a short message that will be sent as an MMS to you (the person that missed the call).
The service captures and records for you all of the calls you have missed, then sends you an audio file as an MMS for you to listen to at your convenience.
Even if your caller has their Caller ID blocked, they can still leave their number. Better still, if the caller wishes to leave an alternative number they can do this too.
The enhanced missed call service is offered for free and is the default for customers that do not want voicemail.
To turn off your Missed Call service, simply dial 159 from your handset and follow the prompts or SMS the word 'OFF' to 159 to deactivate.
Switching the service on simply requires you to dial 159 from your handset and follow the prompts or SMS the word 'ON' to 159 to activate.
