SIM card lock
The SIM card lock protects your subscription, but not the 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
blocked. To unblock it, you need 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.
If the message

message
