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.
To unblock your SIM card
1. When PIN blocked is displayed, enter your PUK } OK.
2. Enter a new four- to eight-digit PIN } OK.
3. Re-enter the new PIN to confirm } OK.
To edit your PIN
