SIM card lock
The SIM card lock protects your
subscription, but not your 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 network operator.
You can edit your PIN and select a
new four- to eight-digit PIN.
