Thanks so much for your support, you are absolutely right about Quectel_LTE&5G_Linux_USB_Driver_User_Guide_V2.0.pdf. I will change my kernel like you advice and report the result.
I will wait for latest RIL library.
May you please explain, what I need to do to start TelephonyManager? Should I edit config.xml?
May you also please explain, is it necessary to mention android.hardware.radio.depercated IOemHook in manifest.xml? I didn’t mention that, because if I mention, it restarts the radio interface every 5 minutes (wifi, ril-daemon and etc) I have no idea how to fix this.
