5.6 Verification of the PIN code
The PIN code is essential in order to make a call or to accept a response coming from the GSM network.
This code is held in the SIM card and can be modified by the user.
To check that the PIN code has been previously entered, use a communication software like Hyperterminal,
and enter the command
AT+CPIN?

5.7 Verification of the modem registration
1. Ensure that a valid SIM card has been inserted in the SIM reader of the modem.
2. Using a communication software like Hyperterminal, enter the following AT commands:
AT+CPIN="xxxx"
to enter the PIN code. The user has only 3 attempts to enter the PIN code. After
the third attempt, only a second code (PUK code) supplied by the operator, will
allow you to choose a new PIN code.
