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 service provider.
You can edit your PIN and select a new four- to
eight-digit PIN.
