[UPDATE]


If you are on Vodafone and you are having problems with Telefonica_UK_Commercial, try India-VoLTE-Vodafone instead.
The name of the country doesn't matter, its all about the actual configuration settings stored in the profile.
you can select profiles of your chosing and report back your country, carrier, and settings you got to get it working and we'll keep a list

The German carriers have enabled VoLTE for quite some time already and OnePlus has officially enabled the feature, but we were still not able to actually use it, only to show it in the settings because the carriers have not distributed OnePlus with the appropiate settings for VoLTE + VoWiFi.

Original credits go to jamal2367 from https://android-hubo.de/thread/8203...t-dual-volte-vowifi-freischalten-de-ohne-root

Requirements:
OxygenOS
With root-->magisk--> Module VoEnabler 1.2 by Toucan-->enable it
w/o root--> open the dialer: *#800# --> oneplus Logkit --> Function Switch --> enable VoLTE + VoWifi switch

Disclaimer
You can break your phone, so know what you do


Steps
1)To be safe, make a backup via TRWP of your EFS partition BEFORE you flash anything! If you're not rooted, do a nandroid backup via fastboot

2) Download and install:

Just use the standard settings and click on OK, next, ...

3) Connect your phone to your laptop via USB

4) open dialer app and enter *#801#
Set Serial and Full-port switch to ON

5) Open "PDC" in your QPST start menu folder, best to do by right click & "run as administrator"
Select your device, right click on "Oversea-Commercial_DS" and deactivate Sub0 and Sub1
Click on Oversea-Commercial_DS again and click on remove -- DO NOT CLICK REMOVE, JUST DE-ACTIVATE IT - your settings stick after a reboot, so no longer need to remove the profile (at least on my device my profiles stick, also makes it easier to go back to default)

6) Close the app and reopen it

7)
Select India-VoLTE-Vodafone or Telefonica_UK_Commercial, right click and SetSelectedConfig for both Sub0 and Sub1

8)
Click on the profile from step 7 again and click on Activate
Yes, select UK/India even if you are located in another region (see above for comfirmed locations + carriers)

9) Restart your phone

10) Voila, you now have working VoLTE + VoWiFi

I don't have "enable VoLTE + VoWifi switch" in the LogKit->Function Switch menu. My model number is GM1913.

Edit: there's an updated LogKit apk that fixes this in the other VoLTE thread.

Not working USA Verizon GM1917 9.5.6 and as soon as you enable it SMS is disabled also.
VoLTE working without the switch. Has to since the phone has no CDMA.

I think you can try this method if this works or not. Go to phone dialer and dial *#*#4636#*#* and select phone information.

In the below screenshot, see for reference.

If I enabled VoLTE using LogKit and it's working, do I have to follow OP instructions?

I have also noticed that volte is working 100%, but VoWiFi is working only after restart, and only until first WiFi network change.

That's the nature of Vowifi
If Volte is working, no need to follow this guide

    Engineer mode apk
    Install->Reboot->*#801#->Full-port switch: ON
    8
    small note
    in order to enable port switch without any apk, just do following [needs root]
    open adb connection in terminal and follow steps
    Code:
    adb devices
    adb shell
    su
    setprop sys.usb.config diag,serial_cdev,rmnet,adb
    the phone will disconnect from adb and PDC will be now available
    wanted to post it in case OP blocks this apk way

    Been meaning to post here for awhile in case any Australian users come across this thread.

    Can confirm that this works beautifully on my 7 Pro with Optus, using the Telefonica UK option.

    Fully working VoLTE and VoWiFi.

    Many thanks to @virtyx @jamal2367 @dagoban for all your efforts with this! :good::good:
