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.
PIN and PUK code
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 operator.
