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.
