Issues with SIM on nRF9151DK: CME ERROR 13 with AT+CPIN?

[gmassana]

Hi,

I’m currently working with the nRF9151DK and using the nrf_modem_lib to test some AT commands. However, I’ve encountered an issue with the SIM.

When executing the AT+CPIN? command, I receive a CME ERROR: 13.

I’ve tested with two different SIM cards, both of which came with the DK (Onomondo SIM and Wireless Logic SIM). Both SIM cards are correctly activated and do not require a PIN.

Initially, I noticed that there was no voltage on the SIM_1V8 pin. However, after setting the modem radio to full functionality with AT+CFUN=1, the voltage appeared, but the AT+CPIN? command still results in CME ERROR: 13. I also tested other AT commands, such as AT+CCID, but this returned a CME ERROR: 0.

Is there anything I might be missing in the initialization or configuration of the modem?

Additional Information
SDK version: 2.8.0
MFW: 2.0.2

Thanks,

Hi Gerard,

Could you try testing the AT Client sample and then see if the modem connects to the network.? It is just to verify the connection first, which likely would be the reason that you receive the error message CME ERROR: 13.
