    I can , but I don't want to.

    Hehe, joking.

    I used that guide on my op8pro and it works.
    But you loose new OnePlus logkit and other features, especially when taking logs.

    ATM I don't need volte. And I hope that OnePlus will enable it in near future by default :)

    Tried and doesn't working because no drivers for OP 9. For now is useless until we find USB drivers for OP 9.

    sorry to reply to an old post. Just got my 9 pro having come from an 8 pro. On the 8 pro there was an option to prefer wifi calling. I dont have that on the 9 pro. Anyone help? When I go to airplane mode and then switch wifi on I get wifi calling so I know it works. I would just prefer to have it on all the time.

    I am sending my Oneplus 8 pro back to amazon for a refund tomorrow.Do not understand why Oneplus disables the VOLTE and VOWIFI menu options and then if you want them expects you to fiddle about installing software etc, which i did try a few guides on Youtube,none of which worked.I see the oneplus 9 pro has exactly the same issue. Crazy and highly frustrating experience.
