    After the update of 10.3.8 in my OnePlus 6, the update corrupted my primary SIM network which caused no more functionality of VOLTE and VOWIFI.
    Has anyone else faced the similar issue? If yes, then how you resolved it?

    Yes- And both the features are toggled on too. My secondary sim is working fine and offering both the features which was kept off at the time of update FYI.

    What is your primary SIM provider? Were you able to use VoLTE before the update on your primary SIM ?

    Primary sim service provider is Airtel India and yes I was able to use both VOLTE and VoWiFi features prior to the update. Even seconds ago before I had to reboot the device to compete the update.

    Try to reset you network settings under settings and than reboot.

    Already done. So is the factory reset.
    Currently in communication with the service provider who have stated that the problem arose due to the update patch that scrambled the network settings to the core.

    I don't have the issue. I too updated to 10.3.8 and everything is alright. I too use an Airtel sim.

    See- that's the beauty of the concern. I even went to the OnePlus service center to get the problem fixed, but they deflected it to the service provider. So, now I am taking up it with the service provider who has no choice but to solve the issue as I have already paid to OnePlus but I my service provider want me as its customer.
    OnePlus is done with it and so am I.

    Or probably might have been a freak coincidence.
    Airtel is no saint. I have had many issues with them.

    In any case, type *#*#4636#*#* and check if the volte and VOWIFI buttons are on.

    Hi,
    I wanted to turn on my VoLTE and VoWifi features in my OnePlus 6 and started to search threads and I've found this old one.

    I've used your code (*#4636#*#*), and when I reach the settings panel, both volte and VoWifi options are turned off and grayed out. Do you know how to turn them on?

    Then you need to contact your network provider. They have to enable it.
