Some SIM cards are protected with a PIN (Personal Identity Number) at the time of purchase. 
If the SIM card lock is activated, you have to enter the PIN every time you turn on your PC and open 
GC79 Manager. If you enter your PIN incorrectly three times in succession, the SIM card is blocked 
and you need a PUK code, from your network operator, to unblock the SIM card.

Only activate the SIM card lock if you know the PIN code.

You have to use your PIN code to turn the SIM card lock off.
