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
PIN
blocked
. To unblock it you need to enter your “PUK”
(Personal Unblocking Key). Your PIN and PUK are
supplied by your operator.

Phonelock
The phonelock protects the phone against unauthorized use
if it is stolen and the SIM card is exchanged. It is not on
when you buy the phone. You can change the phonelock
code (0000) to any four- to eight-digit personal code. The
phonelock can be set to on, automatic or off.
Note!
If the message Codes do not match appears, you
entered the new PIN incorrectly. If the message
Wrong PIN appears, followed by Old PIN, you
entered your old PIN incorrectly.
