Question regarding modem

[AntonReiser]

Good luck!

You did it!

Thank you!

After executing 'AT+QCFG="ims",2' the response was '+QCFG: "ims",2,0' and now I can send as many messages as I wish without a single one getting lost. During phone calls 4G keeps working.

That's such a relief! I had thought the phone would end up im some drawer for defunct electronics.

The list looks as you suggested it should:

Code:

mobian@mobian:~$ mmcli -m any --command='AT+QMBNCFG="List"'
response: '+QMBNCFG: "List",0,0,0,"ROW_Generic_3GPP",0x05040820,202009031
+QMBNCFG: "List",1,0,0,"VoLTE-ATT",0x0501033C,202004261 (...)

However, I have now tried it several times after restarts and sometimes the response is not the desired 2,0 but the unwanted 2,1.

In that case the --command='AT+CFUN=1,1' did not help: 

Code:

mobian@mobian:~$ mmcli -m any --command='AT+CFUN=1,1'

error: command failed: 'GDBus.Error:org.freedesktop.ModemManager1.Error.MobileEquipment.NotAllowed: Operation not allowed'

Anything I can do about that?

Whatever the turnout of  'AT+QCFG="ims",2', after a restart all that is lost: The response to 'AT+QCFG="ims"' is again 1,1 (sometimes 1,0) and not 2,0 (or 2,1).

Is there a way of making the change permanent?
