    Dear support team

    My cellular Service Provider already activated VoLTE and work great with iPhone/Samsung phone/huawei

    when i use OnePlus 8 Pro i can not see Volte active.
    I have installed OnePlus logkit app and enable it from *#800#
    >function switch >enable VoLTE.
    its work after that but unfortunately when someone called me it’s showing unknown caller

    we appreciate your support and many thanks in advance for awesome work

    i live in Saudi Arabia and my service provider STC

    Kind Regards,

    AbbasiG , via OnePlus 8 , Oct 26, 2020 :
    Solution to this problem was very simple,it was to connect with QPST/ PDC and change modem profile , but after android 11, access to PDC is restricted to rooted devices, therefore no solution as of now.

    And i noticted calls on 3g delay while connecting , but on VOLTE ,one can connect directly within seconds to other person...
