I have OP7T Android 11.0.3.1, I did the manual and the VOLTE works. The WIFICALL does not work.
I am in Israel and the operator is Cellcom.

What can I do?

UPDATE: Apparently Telenet only activates VoLTE and VoWIFI on a per SIM basis. The thing you have to do is the following:

1. Ask their support to activate VoLTE and VoWIFI for your number, they'll happily do this for you.
2. I don't know if this has made a difference or not, but when they activated I had the Swisscom MBN from the MI9T pack installed. Try it for yourself with the default to see if it works.
UPDATE 2:

If you want both VoWiFi and VoLTE with Telenet you need the following MBN from the OP 9 Pro:
https://github.com/vcyzteen/oneplus...ric/EU/Telenet/Commercial/Belgium/mcfg_sw.mbn
(File also in attached ZIP for if it were to disappear from Github)
It is the only one so far that has working VoWiFi for me (Tested on OP 7T pro). Of course you still need to ask their support first to activate it, otherwise it won't work. Thanks to @Dracozirion who sent me this link!

Worked on the 11.0.5.1 update using the Freedom mbn for Shaw Mobile. Only minor gotcha is that I am running Windows 11 now and needed to repair my QUALCOMM driver for the port to recognize the device.

Thanks man, I tried CMD and PowerShell with engineering mode, full port switch and diag mode, all came out failing to turn it on, btw I checked with DIGI where I already got SIM ready for VOLTE

Only couple suggestions I have are to wait at least 24 hours since activating ims with your carrier. Other than that use *#*#4636#*#* and under phone info and the 3 dots in the top right check if ims shows unavailable or not? Especially if the other steps for enabling VoLTE and VoWifi have been enabled in the other setting areas with *#800 and under phone settings.

This guide still works perfectly. Recently updated a OP7 to latest OOS 11.0.5.1.GM57AA

It works immediately on reset with both optus and telstra carriers using the Telefonica UK commercial carrier settings. efs\eu\telefoni\commerci\uk\mcfg_sw.mbn
 
Works perfectly (VoLTE and VoWiFi)! OP7 Pro 11.0.5.1.GM21BA

It works great with Polish carrier PLUS (It requires additional activation on carrier's helpline)
Used eu\dt\commerci\pl\mcfg_sw.mbn from mi9t mbns

For Nepal use this file to enable volte and volte wifi.
Hi, the file you have provided does not properly and also telefonica uk mbn file is also not fully compatiable with Nepal Telecom. SMS cannot be received. I have found the correct solution and currently using it. This mbn file is from MI11-Ultra and the mbn file is from DIGI (inside SEA). now I am fully able to use volte, vowifi and even i can receive sms for Nepal Telecom.

You can use the MBN files from M11-Ultra. It has all the Malaysian telco including (Umobile/Celcom/Maxis/Digi/TM/YTL) as well as other updated telcos too. currently, I am using DIGI mbn profile and it works perfectly for my Digi telco. you can extract it and directly use it >>

    Hi everyone.


    Code:
    /*
    * Your warranty is void. Or vaild, probably?
    *
    * I am not responsible for bricked devices, dead SD cards, Ebolation X,
    * thermonuclear war, or the current economic crisis caused by you following
    * these directions. YOU are choosing to make these modificiations, and if
    * you point your finger at me for messing up your device, I will LMAO at you.
    */


    First you will need that apps:

    EFS Modded 1.2
    EFS
    mbns-mi9t.zip can use this or can use this Pixel mbns
    OEMLogKit_1.0-1.apk
    EngineeringMode.apk

    NOTE: ON custom ROM OEM and Enginer mode does not work. See step 5.1 for custom ROM.
    1. Enter * # 800 # in the stock dialer, and then click oneplus Logkit - next - Function Switch - next - activate VoLTE switch, VoWifi switch and VT switch.
    2. Reboot device.
    3. Install Qualcomm QPST Diag port x64 / QPST 2.7.474 software on your computer
    4. Unzip EfsTools from above, open up a cmd window and cd to the directory where you extracted it. Depending on how you connect to diag you will need to modify EfsTools.exe.config - if you're connecting via USB you most likely won't have to do anything as it will find the port automatically, unless you have more than one port, in which case you can simply change port from Auto to the COM port of the phone (for example COM13).
    5. With your phone connected via USB enter *#801# and check Engineer Mode Toggle switch to ON.
    5.1. If you are on custom ROM you activate the enginer mode by entering in adb shell and run the next command:
    setprop sys.usb.config diag,serial_cdev,rmnet,adb
    5.2. Also if you are on custom rom you can use this method or the PDC one, also not using OEM and engineer, just run command from 5.1 and you should see your phone in PDC.
    6. You can test the connection by running this in the cmd window:

    Code:
    EfsTools.exe efsInfo

    Should return something like this:
    efsInfo.PNG



    This should report back some info if everything is working.

    7. Extract efs.zip from above to the same directory as EfsTools.exe, and make sure the mcfg_autoselect_by_uim file is there. Now simply run this in the cmd window, one line at a time:

    Code:
    EfsTools.exe writeFile -i mcfg_autoselect_by_uim -o /nv/item_files/mcfg/mcfg_autoselect_by_uim
    EfsTools.exe writeFile -i mcfg_autoselect_by_uim -o /nv/item_files/mcfg/mcfg_autoselect_by_uim -s 1


    If everything worked you should see no error messages.

    The mbn directory structure is generally laid out like this: <region>/<carrier>/commerci/<country>/mcfg_sw.mbn. For example, the one for my carrier is eu/h3g/commerci/se/mcfg_sw.mbn. Copy the mcfg_sw.mbn file to the same directory as the EfsTools.exe, then go to the cmd window you opened and type this:


    Code:
    EfsTools.exe uploadDirectory -i mcfg_sw.mbn -o / -v
    
    EfsTools.exe uploadDirectory -i mcfg_sw.mbn -o / -s 1

    8. If it has worked you should see a bunch of output, but no errors. Try rebooting now, and hopefully after it has booted you will have fully functional VoLTE and VoWiFi.

    If you manage to activate VoLTE/VoWiFi using this guide please let us know your Country--Carrier--MBNS that you used.

    *****UPDATE*****

    So played around again today with the port selection after reading up more about the error.
    Going from others with higher versions of Android 11 on the OnePlus 8 and 9 phones, it appears you have to select:

    Rndis,diag Switch instead.

    I have tried it tonight and can say, it successfully worked!!
    Got VoLTE and VoWIFI working again on a OnePlus 7T Pro with 11.0.3.1.HD01AA August 2021 patch.

    Using Telstra AU network.

    I have extracted the MBNs from OP7 Pro. Hope this will help someone.

    Same method worked fine for me, though I got the information and files from different sources, as I have been looking for some days for a solution. Also, it's possible to set the engineer mode using adb, rather then installing the Engineer apk, by writing in adb shell setprop sys.usb.config diag,adb
    I used the Telefonika_UK_Commercial mbn from Pixel 4, so far it seems a lot more stable than the one from OOS (on OOS10 it was continuously switching between VoWiFi/VoLTE every few minutes).

    Romania - Digi.Mobil - Pixel's 4 EU\Telefonica\Commercial\UK, if it makes any difference.
