Security Commands
The AT Commands described in this chapter allow the external application to determine various security related
settings.
5.1
AT+CPIN PIN Authentication
controls network authentication of the TC63.
The read command returns an alphanumeric string indicating whether or not network authentication is required.
The write command allows the TC63 to store the entered password. This may be for example the SIM PIN1 to
register to the GSM network, or the SIM PUK1 to replace a disabled SIM PIN1 with a new one, or the PH-SIM
PIN if the client has taken precautions for preventing damage in the event of loss or theft etc.
If no PIN1 request is pending (for example if PIN1 authentication has been done and the same PIN1 is entered
again) TC63 responds "+CME ERROR: operation not allowed"; no further action is required.
