AT+CPIN2 PIN2 Authentication
controls network authentication of the MC55.
AT+CPIN2
The read command returns an alphanumeric string indicating whether or not network authentication is required.
The write command allows the MC55 to store the entered password. This may be for example the SIM PIN2 to
benefit from the features listed below, or the SIM PUK2 to replace a disabled PIN2 with a new one. Note that
PIN2 can only be entered if PIN1 authentication was done.
If the MC55 is requesting SIM PUK2, use
PIN2.
