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

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
1 When PIN blocked appears, enter
your PUK and select OK.
2 Enter a new four-to-eight-digit PIN
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 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.
