    I already switched on the settings but i see no VoLTE logo on top. My mother and brother's phone(Samsung and Huawei) have VoLTE on their phone. We are using same internet provider

    You need to contact your network provider. They activate it by number. Sometimes, there will be an issue.

    If VoLTE is active but no icon. Open Settings>Display>Status Bar>Icon Manager. And enable VoLTE icon.

    If you can't get VoLTE active, try the following.

    This is for all OP phones, however it discuses the 8 Series, but it should apply to any series as the protocols are the same.

    [GUIDE] Enable VoLTE & VoWiFi on all devices NO ROOT.

    Log Kit 1.0

    There are newer versions but I would suggest trying this with the details provided on XDA.

    If you do try the suggestions. Let us know how you get on.

    I found solution for Oneplus 7 series in youtube.

    The way to activate Volte is only use OnePlusLogKit, EngineerMode. apk and Efs tools in this video.
    It is actually in Japanese, but at least you can find a part of solution because mbm on the comment area is only covering Japanese mobile careers. However, once you get mbm from somewhere for your country, you can leverage the way and the command protocol there. The automated subtitles are not fully covered correctly, but you can somehow understand except some words.
    In addition, it seemed not only myself, but also many others succeeded with Oneplus 7/7t/7pro/7t pro. Recommend you to check replies and comments from other users because these might fill your gap.
