Unable to Connect to Network Using Onomondo SIM with nRF9151 DK in India

Dear Onomondo Support Team,

I am currently experiencing an issue with my Onomondo SIM card — it is unable to register on the network when used with the nRF9151 DK board.

I have carefully followed the setup instructions provided in the following guide:

Despite this, the SIM still fails to connect to the network.

Below are the AT commands I used along with the responses received from the modem:

> AT%XSYSTEMMODE=1,0,0,0

OK
> AT+CGDCONT=0,"IP","onomondo"

OK
> AT+COPS=0

OK
> AT+CEREG=2

OK

> AT+CFUN=0

OK
> AT+CFUN=1

OK
> AT+CEREG?

+CEREG: 0,4

OK

Additional details:

  • Device: Nordic nRF9151 DK

  • Location: Surat, Gujarat, India

  • SIM Status: Confirmed active and working in a smartphone with correct APN and roaming enabled

To assist in diagnosing the issue, I have also captured a modem trace screenshot, which I am happy to share. Please let me know the best way to provide this file or if there is a preferred format.

I would greatly appreciate your guidance in resolving this issue.
