SIM card lock
This lock only protects your subscription.
Your phone will work with a new SIM

a PIN (Personal Identity Number).
If you enter your PIN incorrectly three
times in a row, the SIM card is blocked
and you need to enter your PUK
(Personal Unblocking Key). Your PIN
and PUK are supplied by your network
operator.
