    I've searched the threads and cannot get wifi calling enabled.

    I'm using Oxygen 10.0.12 with a 7t on the AT&T network in the US.
    Sim slot 1, mobile data enabled.
    I just switched from and iPhone that had wifi calling so I know that AT&T has this feature.

    I've tried the *#800# method. I see that my VoLTE is enabled, but there is no box or wording to enable Wifi Calling.

    Any suggestions on how to enable Wifi Calling?

    Thanks

    I dont see wifi calling option on my phone. I relocated to a place where the phone signals are not great, ATT, Verizon both suck here. I was hoping to see wifi calling but I dont see that option at all. This looks like a oneplus 7 pro issue rather than verizon. Is there going to be a patch for this soon?

    If you don't have it by now... Then don't expect it for a 3yo device.

    You can manually enable it by using logkit if you want

    Despite a lot of threads on this, OnePlus doesn't seem bothered about fixing such a small functionality on their handsets which they ironically call Flagship devices.
    This small feature is VoWiFi or Wi-fi calling.
    I have seen a lot of threads but no thread has a solution.
    VoWiFi works fine for a while but goes away very soon. It is small yet a much needed functionality.
    This feature works perfectly fine on a low end Nokia handset and ALL OF SAMSUNG DEVICES that support wifi calling. There is a reason why still Samsung has such a good user base. Because of such issues OnePlus might never be like them.

    After update OP5T to Android 10, missing switches to VoWiFi and VoLTE.
    In this tutorial i will show how to fix this.
    It is enabling VoWiFi and VoLTE even in Poland with T-Mobile, Orange and Play carrier.

    This method doesn't required root.

    0. Make sure that you just enabled the VoWiFi and VoLTE in your carrier first !!!
    1. Download and install the old LogKit:https://www.apkmirror.com/apk/onepl...lease/onepluslogkit-1-0-android-apk-download/
    3. Type *#800# --> oneplus Logkit --> Function Switch --> enable VoLTE and VoWifi switch
    4. Open Settings --> WiFi & Intenet --> SIM & netwok --> enable VoLTE and VoWifi switch
    5. Connect your phone to PC
    6. Type *#801# in Phone app and enable Serial and Full-port switch
    7. Download and unzip the EfsTools with config files includes: https://drive.google.com/folderview?id=1CUPpk5xGoV3cH6HTFLJSIZuavY5tW5Qm
    8. Open CMD as Administrator on the PC, navigate to the folder where you extract the files (eg. cd c:\EfsTools-0.10-modded-1.2-win32)
    9. Now execute the following commands:
    EfsTools.exe efsInfo

    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

    EfsTools.exe uploadDirectory -i mcfg_sw.mbn -o / -v

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

    Thats it. Commands with "1" on at the end are for the second SIM card.

    On my OnePlus 7t pro the wifi Calling feature gets turned off every now and then.
    Please help me out.
    even the wifi and mobile network automatically turns on and off.

    thank you. I installed Logkit and enabled the volte and vowifi switch, after restarting the phone I enabled volte/vowifi in SIM settings. Now VoLTE works fine. My carrier does not support vowifi. I did use Efstool. Is EfsTool necessary to activate the VoLTE and VoWiFi?
