In this function, the command “AT+CCID” is used, but I have searched the 3GPP TS 27.007 document and did not find this command.
Thank you for pointing out this command. Cellular_CommonGetSimCardInfo is provided for porting convenience. The port can still use their own implementation for Cellular_GetSimCardInfo like the BG96 reference port.
We will create a PR to note this command and add configuration for backward compatibility with existing port.
