+EPIN, Enter SIM PIN2 to Verify PIN2 Indicator
This AT command will be used to verify the PIN2 when the proper SIM PIN2 password has been
provided. The code presented by the ME PIN2 password will be compared with the relevant one
stored in the SIM. The execution of this command is possible only if the SIM is in READY state
or waiting for PIN2 state. If the PIN2 presented is correct, the number of remaining PIN2
attempts will be reseted to its initial value allowed by the service provider. If the PIN2 presented
is false, the number of remaining PIN2 attempts will be decremented. If an incorrect password is
entered for maximum attempts allowed by provider, the SIM will be blocked, and the user will
have to unblock it. To unblock the SIM card, the user can use the AT+CPIN command.
The following table shows the +EPIN parameters.
