    Hello, I have an active subscription for the VoWifi feature by the Hungarian T-Mobile, they confirmed it is on and available, still, I cannot enable it on the phone, there's no option among the SIM card's settings. The provider told me my phone, most probably, doesn't support their profile. I use the most current EU ROM, 10.0.6. Will it be possible with the next release?

    I had a call with one of your colleagues on the 3rd of November regarding the VoWIFI on my OnePlus 7 pro phone, he told me I'll get another call soon where we will go further with the investigation. It was 19 days ago and I didn't receive any calls since that. Do you know if there is any progress in my case?

    The VoWifi switch appeared in Open Beta 19, set the call preference to "call on Wi-F", but still, my device uses VoLTE, the icon doesn't show up on the notification bar, neither in the calls.
    I tested if I place my SIM card into another phone and there it worked. The phone I used was a Samsung Galaxy S20.

    Additionally, it worth to mention I didn't hear back from you in the recent 20 days; neither a call, neither a written message.

    This case can be closed. I had a discussion with Levi George on the live chat and he confirmed this function is available in the latest stable ROM, 10.0.10. I installed and tested that, it really functions as I expected.
