Protecting your SIM card

You can lock the SIM card to prevent unauthorised use of the card, even if it is removed and inserted into
another phone. Once the SIM card is locked, it must be unlocked each time the phone is turned on. If the
unlock code is entered incorrectly 3 times, it can only be unlocked with the operator-provided PUK (Personal
Unblocking Key).
