    You don't need to enable VoLTE. Insert the Jio (VoLTE enabled) in any slot. By default, VoLTE will be active. If it is not, you can change the network preferences from Network option in settings.


    1. Go to Settings > Call Settings (Sim and Network)
    2. Tap Cellular networks > Enable Voice over LTE On/ Off.

    2. Choose Phone information.
    3. Click " Phone Information" and Toggle VOLTE Provisioned.
    4. Restart the phone and you are done.
