Please note:

The GSM module must not register when you select a forbidden operator manually! Otherwise, you will not be able to set up any more connections. Display the list to find out which operators are forbidden and which are allowed. Use the AT+CREG command to find out whether or not the GSM module is registered. You will also be unable to set up any connections if you have set mode n to “2” (sign off of network).

AT+CPIN - Enter PIN and query blocks

The PIN (personal identification number) is provided to prevent unauthorized use of the GSM module. The PIN is usually a 4-position secret code. If this block is activated, you must enter your PIN before you can use the module’s full range of functions. When you query the status, the system displays result codes relating to the chip card and tells you either that you must enter a PIN or that the chip card has already been read, in which case PIN entry is unnecessary.
