Set Up Call Forwarding & Waiting in OnePlus 2, X & 3 (Oxygen OS)

OnePlus smartphones run a customized version of Android. The company brands this operating system as Oxygen OS, and since it is customized, many settings aren’t where you expect them to be. This also applies to the call settings viz Fixed Dialing, Voicemail, Call Waiting and Call Forwarding. Some settings are slightly displaced; some are more. Unless you end up looking up at each and every setting, you will probably never find it.

Configure Call Waiting, Forwarding & Fixed Dialing in OnePlus

Follow the steps below to access the call settings screen where various operator specific call settings can be configured. These include – SIP Settings, voicemail, call waiting, conditional call forwarding and call barring. Applies to: OnePlus 2, OnePlus 3, OnePlus X and any other device running Oxygen OS.

    When not reachable. I am trying to turn off this. But getting error ” your carrier doest allow this service when phone is unreachable. What this carrier means and how I can change this.

      Carries usually forward a non-reachable number to the voicemail or their own system so that they can record missed calls when the phone wasn’t receiving network. Some carries don’t allow you to disable this but you can add a custom forwarding number. So, it gets to this default when you don’t have a custom forwarding number.

    • Narender Singh January 11, 2017 at 12:37 pm #

      Call conferencing works fine for me here. As it is also an operator dependent service, please make sure that your operator has enabled Conferencing on your number 🙂
