Protecting the SIM Card
Your PIN (Personal Identification Number) code protects the
information stored on your SIM card. When the SIM PIN feature
is activated, you must enter your SIM card PIN code each time
you turn on the phone or insert a SIM card. Your SIM card PIN
code is given to you by your service provider.

Unblock the SIM Card PIN Code

If you enter an incorrect SIM card PIN code three times in a row,
your SIM card is disabled and your phone displays the message
  !. You need to enter a PIN unblocking key (PUK)
code, which you can obtain from your service provider. After
entering the PUK code, you will be prompted to create a new
SIM card PIN code.
