SIM Card Lock
The SIM card lock protects your subscription,
but not the phone itself, from unauthorized use.
If you change SIM cards, your 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 service
provider. You can edit your PIN and select a new
four- to eight-digit PIN.
