RM502Q-AE not getting IP address

,

I am using the Quectel RM502Q-AE module and encountering several issues during operation. Here are the problems I am facing:

  1. When connecting via the QMI script/MBIM, the connection is not established.
  2. On running the script, the wwan0 interface does not acquire an IP address at all.
  3. When trying to activate the PDU context using the command AT+CGACT=1,1, the command fails, and the context does not activate.
  4. receiving these messages
    AT+QCFG=“usbnet”,0
    ERROR
    AT+QCFG=“usbnet”,2
    ERROR

It is abormal. Please check whether the AT command you sent is correct.

Please check

AT+CGDCONT?
AT+QENG="servingcell"
AT+CPIN?
AT+CFUN?
AT+CGACT?

Yes the commands i have sent are correct seems to me.

The required output are
OK
AT+CGDCONT?
+CGDCONT: 1,“IP”,“internet”,“0.0.0.0”,0,0,0,0,“”,0,0,0,0,“”,0

What’s the operator?

we are using 99940 PLMN with open5gs. some extra logs are

AT+QNWPREFCFG=?

+QNWPREFCFG: “restore_band”
+QNWPREFCFG: “policy_mode”

OK

+CIEV: 1,4

+CIEV: 1,0

It is not registerred.
I think you need to check the band first.
Whether the band set in the Open5GS is supported by RM502Q-AE.

any trouble shooting guide?? because i checked all the required items and its fine.
