Call not working on Redmi Note 9 pro with ubuntu touch installed

[iqrajaved]

Hi everyone,

I have installed ubuntu touch 20.00 stable version on Redmi Note 9 pro. The problem I am facing in it is that I cannot call using the phone and no call is being received.
The messages are working fine however.

Please let me know what to do about this?

Thanks

@iqrajaved I don't have this phone but check your apn(s) first.

@iqrajaved It definitely works for other people I know using this phone. I would presume this might also be caused by incorrect firmware, though the fact sms works is interesting and may lead to a different problem, not sure. Yet still I am going to ask. Did you start by installing Android 10 as suggested by the installer in the process?

Generally this is the firmware that is recommended for joyeuse at least:

• 12.0.2.0.QJZMIXM

I know why this call error happens to a lot of users. To cut a long story short, install the standard Miui version again. Please note that it is very important to turn off all switches for Google services, location services and updates during installation. You will be asked to do this during setup, then start the device and switch on developer mode. Start the device in fastboot mode and install Ubuntu.
