How to Add, Change or Remove Call Diversions: Mobile Phone

The easiest way to set up diversions for your mobile is through the My Optus app. You can set diversions simply to voicemail, or you can specify a number to divert your calls to (ie. such as a landline number).

Diverting your calls is as simple as the following:

  1. Open the My Optus app and click the "menu" icon on the top left corner of the screen

  2. In the menu select Settings and then Setup call diversions

  3. You can now setup diversions for the following:

    • All Calls: This is an unconditional diversion of all calls

    • On busy: Calls will only be diverted when you're phone is busy

    • No answer: Call will be diverted when you're not able to answer your phone

    • Off/No coverage: Call will be diverted when your phone is off or in an area that has no coverage

If you're not able to setup diversions via the My Optus app, you can divert calls from your mobile to another phone number by following 2 simple steps.
