AFAIK, when you buy a SIM card, you are given a 4-digit PIN number,
which is the only means of authentication between the end-user and the
GSM part of the phone. So, we have to live with that.

After connecting to the GSM modem [1], you will get get an error for
AT+CIMI (International Mobile Subscriber Identity) if you don't enter
the pin details in CPIN:

AT+CIMI
Error

You have to authenticate first (follow these step) before you can get
a proper output from AT+CIMI:

AT+CPIN="xyza"
OK
AT+CIMI
<some-15-digit-number>

Regards,

SK
