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
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.
