SIM card protection

The SIM card lock only protects your subscription. Your phone will still work with a new
SIM card. If the SIM card lock is on, you have to enter a PIN (Personal Identity Number).
If you enter your PIN incorrectly more times than the maximum number of attempts
allowed, your SIM card will become blocked. You need to enter your PUK (Personal
Unblocking Key) and then a new PIN. Your PIN, PIN2, and PUK are supplied by your
network operator.
