And during real phone cards somehow it’s random if the call works or not. Even if I have best 4G connection (something my FP3 calls 4G+) I often can’t hear the other person and the other person can’t hear me. It doesn’t matter if they’re calling or I’m calling.

Can’t find exactly in which topic it has been discussed (this one perhaps?), but suggested workarounds were disabling wifi calling or enhanced LTE mode.
A suggested workaround is to disable “Enhanced LTE mode”.
