    This way is very similar with how it was done on OOS10, but root is required.

    Steps:

    1) Open the dialer: type *#800# > Function Switch > enable VoLTE + VoWifi switch
    2) Connect phone to PC, make sure it works with adb and run "adb shell"
    3) Type "su" - allow superuser access on phone
    4) Type "setprop sys.usb.config diag,diag_mdm,qdss,qdss_mdm,serial_cdev,dpl,rmnet,adb". At this step, phone will disconnect and reconnect to your PC.
    5) Open PDC app (it will be visible now)
    6) Select Telefonica_UK_Commercial or UK-VoLTE-Vodafone or w/e worked for you with OOS10
    7) Right click and SetSelectedConfig for both Sub0 and Sub1
    8) Select the same profile with Step 6 and press "Activate"

    VoLTE/VoWiFi should work now.
