Sorry, I can’t help you with audio. It’s not a feature I’ve used with a modem, so I have no experience to draw on.

23

Seems that you need an exetrnal CodoC.

24

Ya I have external codec connected over IMX8mp Board.

+QDAI: (1-12),(0,1),(0,1),(0-5),(0-2),(0,1),(1),(1-16)

OK

+QDAI: 3,0,0,4,0,0,1,1

OK

Card 1 tlve320aic is our codec on Board.

I mean that there should be CodeC connected with the EG25G but not on the IMX.

Please check the reference desgin.

+CNMI: 2,1,2,1,0

output.

28

That setting should not interfere with incoming SMS storage. It isn’t the cause of your problems there.

I’m currently out of ideas as to why you cannot send or receive SMSs.

29

I’m now wondering if you need IMS for SMS on the network and access technology you’re roaming on.

Please report the results of the following AT commands:

AT+CGDCONT?
AT+QCFG="ims"
AT+QCFG="ims/ut"
AT$QCPDPIMSCFGE?

You have the IMS APN set in context 2 already. Maybe SMS will work if you try to activate it using:

AT+QCFG="ims",1
AT$QCPDPIMSCFGE=2,1

Then power-cycle the modem.  Good luck.
