SIM card lock
The SIM card lock protects your subscription, but not your 
phone itself, from unauthorized use. If you change SIM cards, 
the phone still works with the new SIM card.
Most SIM cards are locked at the time of purchase. If the 
SIM card lock is on, you have to enter a PIN (Personal Identity 
Number) every time you turn on your phone.
If you enter your PIN incorrectly three times in a row, 
the SIM card is blocked. This is indicated by the message 
PIN blocked
. To unblock it, you need to enter your PUK 
(Personal Unblocking Key). Your PIN and PUK are supplied 
by your network operator. You can edit your PIN and turn 
off your SIM card lock at any time.
To unblock your SIM card

edit your PIN, you entered the PIN or PIN2 incorrectly.
