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

a row, your SIM card is disabled and your phone displays
SIM Blocked . You must enter a PIN unblocking key (PUK)
code, which you can obtain from your service provider.

press must occur within two seconds of the previous
keypress. If the unblocking attempt is tried unsuccessfully
