How to Add or Remove Missed Call Service: Mobile Phone

The 'Missed Call Service' is an alternative to voicemail that sends you a text message advising you of a missed call.  The service captures and records the calls you have missed if you're out of range, have your phone switched off, are busy on another call or simply don't want to answer your phone.

Missed Call Service differs from the premium voicemail feature, Voice to Text. Which, among other benefits, converts actual voicemail messages to text.

Note.  Effective 2 November 2015, the Optus Surepage service has closed down. Not to worry though! As an alternative, you can choose between Voicemail or the Missed Call Service.


How does it work?

When the Missed Call Service is active, if a caller can’t reach you, they will hear the following recording:

"The person you are calling is not available. Please leave a short 10 second message after the tone and we will send it as a text message"

The Missed Call Service then notifies you via SMS of the missed call or the short message that's been left.


What does it cost?

What's the difference between...

SMS Me

Is part of our regular voicemail service and has no additional charge. It simply sends you an SMS advising when a new Voicemail message has been left.

Missed Call Service

Is a free substitute for voicemail. It allows for small 10 second messages to be converted and sent as an SMS but does not record or store the message like Voicemail.

Voice to Text

Is a paid optional add on to voicemail. It converts full Voicemail messages to text and then sends them to you, so that you can reply directly to the caller by voice or text. Further info on Voice to Text is available here.

Voice to MMS

Is a paid optional add on to voicemail. It converts full Voicemail messages to an audio file and sends them to you as an MMS, so that you can reply directly to the caller by voice or another message. Further info on Voice to MMS is available here.
