Mi 10t Lite - VOLTE

[Atanas Chebishev]

Hello. I am from Bulgaria and i have the following suggestion:

I've activated VOLTE on my SIM card. The provider is A1 Bulgaria.
And the service is working fine with other phones (Mi 10 lite, Huawei p40 lite, Mi note 3), but it doesn't work on my phone.
The reason is simple: The default profile for a1 bulgaria in the modem settings..
I've checked other profiles and it works (Vivacom Bulgaria and the ROW_commercial profile).
So my suggestion is to be done something with the a1 profile, because it is useless
I've used this line of code on rooted device(adb shell -> su:
setprop sys.usb.config diag,serial_cdev,rmnet,adb

it activates diagnostic port 9091(you need this driver also: https://drive.google.com/file/d/11K0HCfMYo9BDiOFt3RooLDj8U5ftJbv-/view )
and after that with QPST/PDC tool you can see and change the profiles.

I don't know if the problem is in the modem, in the chinese base rom or in a1 bulgaria, but i am providing a solution for a1 users.
It will be good if the working config is used by default.

Thank you for you attention

The PDC tool works but I can't EFS Explorer to work - Did you have any success with that?
