    I've been searching all around, called my Carrier support, opened a Bug report on OnePlus for this issue posted around the forum, no one was able to help.

    I even have a thread (where i will link this one) asking people with whom it worked and didn't work... and now i found the solution. I just tested on my 7pro, and it worked!

    Follow this link and the article, and report back to see if it works!


    I'll be happy to know if i helped some people!

    the apk is not needed
    use dialer and dial *#800# to get to the same menu
    also keep in mind you are essentially forcing this function on
    Ive done this on my 3t and while volte was working perfectly I had to disable vowifi since every call that wanted to come through using this method was giving the engaged sound on the other end
    worth a try but make sure you test it properly

    Not all have, i didn't have it on 1.0, I installed 1.0-1 and it appeared. On the 1.0 i didn't have the VoLTE or WifiCalling in the LogKit.

    You have to call Verizon to set it up on their end. It doesn't take too long and it was pretty simple for me. Works great now.

    I have wifi calling feature on the line. Is there something else they need to do?

    Does your screenshot confirm that the roaming options are available for each SIM separately and not just a single option applying to both SIM's?
