This one worked! I had issues with the PDC as it won't detect my phone even after installing the latest Qualcomm drivers.

I'm using a Oneplus 6T.
Running on android 11.1.1.1 - Official
Not rooted.
Sim/Carrier is DITO.
Location: Philippines.

I deleted the oversea commercial profile as it defaults back to it after the adb reboot. I activated the India one instead. I tested and now and calls are working both inbound and outbound :)

Probably the best tutorial I found for my phone for enabling VoLTE :). Cheers!

Reporting back here just in case anyone is watching:
  • OP6T
  • Telstra AU (Boost MVNO)
  • Oxygen OS 11.1.2.2
  • Not rooted.
The update to 11.1.2.2 killed VoLTE and VoWiFi again.

I used the instructions from this thread and then the instructions from https://forum.xda-developers.com/t/guide-activate-volte-vowifi-oos-11-ob1-ob2.4223967/ to upload the pixel 3 mbn to recover. It looks like each security update adds back the default Overseas-Commercial_DS profile and resets the mbn.

Changes:
  1. This thread:
    1. Remove Overseas-Commercial_DS: VoLTE seems to better survive phone reboots with it removed
  2. Thread https://forum.xda-developers.com/t/guide-activate-volte-vowifi-oos-11-ob1-ob2.4223967/
    1. Step 5 - instead of Engineer Mode, Use rndis,diag mode to enable EfsTools

Confirming this. I've just updated to OxygenOS 11.2.2 and it disabled volte as what @BJReplay said, the update restored Overseas-Commercial_DS profile and defaults to active.

I've done the same process which takes less than 5 mins and volte is back up and running for me again.

    Hello! This is my guide to enable or activate VoLTE/VoWIFI on Oneplus 6T OxygenOS 11 Beta

    Before I install OSS 11 Beta, my VoLTE is working fine and I used this method to enable it but after I upgrade it to OSS 11 beta, The VoLTE is not working anymore so after much research I found the solution.

    Tools to be needed:

    ADB
    Oneplus Drivers
    Qualcom Drivers
    QSPT Software

    1st - Connect your phone and run adb on administrator mode and type this command:

    adb devices - make sure that your device is working on adb

    adb reboot ftm - this will reboot your phone into diagnostic mode and you can see Chinese characters there

    adb shell

    then type this command

    setprop sys.usb.config diag,serial_cdev,rmnet,adb then enter

    after that, don't close the command prompt

    2nd - open device manager and make sure on the com port tab, you can see the Qualcomm HS something like that.

    if you can see that the driver is installed, next is

    3rd - open PDC as administrator

    4th -Select your device on the drop-down menu then if you see your device select it and 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)

    5th - Close the app and reopen it

    6th - Select India-VoLTE-Vodafone or Telefonica_UK_Commercial, right-click and SetSelectedConfig for both Sub0 and Sub1

    7th - Click on the profile you selected (India) again and click on Activate
    Yes, select UK/India even if you are located in another region (see above for confirmed locations + carriers)

    8th -Close the PDC and go back to cmd/adb then type
    adb reboot

    and Boom! VoLTE is Working

    I combined the tutorial on this forum https://forum.xda-developers.com/t/guide-volte-vowifi-working-for-german-carriers.3817542/ and my own research.

    Hi does this method need a "root"???
    no need.

    So this method works for PDC tool, I was able to see MBN profiles. I have loaded different one and VoLTE & VoWIFI works as previous, but still only in HD, no in HD+ (EVS codec). So maybe some other tips??? (small remark today I have update to OOS11 Open Beta 2 without change).
    UPDATE: it works !!! I have uploaded by PDC tool mbn profiles, then I repeat process via EFS Tools and it start to work (HD+) EVS Codec, thanks for PDC tutorial.

    Could you share these profiles?
    Of course, soon I will upload them.

    thanks a lot @blackjack1942

    I just tried this on the official android 11 update and it works flawlessly!
