SIM card lock
The SIM card lock protects your subscription from
unauthorized use. 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 and the message
displayed. 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 select a new four- to eight-
digit PIN.
