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. Enter PUK provided by your provider.
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 turn off your
SIM card lock at any time.
