Protecting the SIM Card
Your PIN (Personal IdentiÞcation 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 
SIM Blocked....

160Caution: If the unblocking attempt is tried unsuccessfully 10 
times, the SIM card is permanently disabled and your phone
