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.
