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

have to enter 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.
To unblock the SIM card

PUK and select OK.

and select OK.

Phone lock
You can stop unauthorized use of your
phone. Change the phone lock code
(0000) to any four-to-eight-digit
personal code.
If you select a city, My time zone also
updates the time when daylight saving
time changes.
If Codes do not match appears, you
entered the new PIN incorrectly.
If Wrong PIN appears, followed by
Old PIN:, you entered your old PIN
incorrectly.
It is important that you remember your
new code. If you forget it, you have to
take your phone to your local
Sony Ericsson retailer.
