/ What is PIN?
PIN (Personal Identification Number) is a password provided by your
network operator. Once activated, your PIN protects your SIM card from
being used by unauthorized people, even if it is inserted in another phone,
unless the correct PIN is given the moment the phone is switched on. This
PIN check prevents a thief from making calls and accessing network services
at your expense and protects the information in your phonebook if your
phone with your SIM inserted is stolen.
To disable the PIN check, go to menu: Settings --> Security settings --
> Set PIN1.

card will be blocked. To unblock the SIM card, you need to
enter the PUK (Personal Unblocking Key) of the card. Please
call the operator, and ask for PUK.
• Your phone can only be used to make emergency calls when
your SIM card is locked.
