To check if the SIM card of the INSYS GSM and the entered PIN were accepted, proceed as

If required, enter the Pin (see Chap. 3.5.1) or the PUK (see Chap. 0).
Checking the PIN using an AT command
1. Enter the command AT+CPIN? in the terminal program.
The following responses are possible:

<+CREG: 0.3>
The status of the login state is indicated by the 2
