SIM card lock
The SIM card lock protects your subscription, but
not the 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 pur-
chase. 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 and the message PIN
blocked appears. To unblock it, you need to enter
your PUK (Personal Unblocking Key). Your PIN
and PUK are supplied by your network operator.
