How to read Subscriber number on NRF9160

[Hannibalhz]

Dear Nordic engineers

I would like to read  Subscriber number on NRF9160.I used AT+CNUM to read Subscriber number.

But it's return  "ERROR".I read AT command document,it says "An ERROR response is returned if MSISDN is not available on SIM card or if SIM card is not initialized."

So I input "AT%XSIM?"，it's return "1".I think SIM card is initialized.

I used the NRF9160DK to test.Its program is asset_tracker_v2(NCS 1.9.1).The modem software version is 1.3.1. My SIM card is NBIOT Card of China Mobile.

I'm quite sure the DK has Joined mobile network. Because the DK has connected NRF CLOUD.

So can you pls give me some good suggestion about how to read Subscriber number?

Best regards.

Hi Kazi

I've know the problem's reason, my SIM card is the NBIOT card of China Mobile. China Mobile does't support this function.  Although, I reply to you too late, but I hope to more people will see this case.

Best regards,
