Verify the PIN code of the SIM card
Power down the modem. Insert a valid SIM card. You should have received a corresponding PIN
code.
The AT+CPIN write command can be used to enter one of the passwords listed below. The read
command can be used to check whether or not the ME is waiting for a password, or which type of
password is required. 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 requested by the ME
AT+CPIN may also be used for the SIM PIN2 or SIM PUK2.
If no PIN1 request is pending (for example if PIN1 authentication has been done and the same
PIN1 is entered again) MC52i responds "+CME ERROR: operation not allowed"; no further action
is required.
Each time a password is entered with AT+CPIN the module starts reading data from the SIM. The
duration of reading varies with the SIM card. This may cause a delay of several seconds before all
commands which need access to SIM data are effective.
We could further verify that the modem has been properly registered to the GSM network. Enter
the
AT+COPS?
command.
