PIN in Terminal-Mode
Enter the PIN
If the LED S blinks slowly (1 time each second), the SINAUT MD720-3 waits for a
PIN entry.
In Terminal-Mode the PIN need to be entered using the AT command AT+CPIN.
Example:
The number of permitted trial to enter the PIN is limited by the SIM card.
Normally three attempts are allowed, i.e. you may enter two times back-to-back a
wrong PIN, at the third attempt the right PIN must be entered, otherwise the SIM
will be blocked. In this case the SIM card can only be unblocked by entering the
PUK.
