SIM card lock

The SIM card lock protects your subscription, but
not your 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 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
PIN blocked. To unblock it, you need
the message
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.
If the message Codes do not match
edit your PIN, you entered the new PIN incorrectly.
If the message appears, followed by
Wrong PIN
you entered your old PIN incorrectly.
