Allows you to set whether the phone will search for a GPRS network
when it is turned on.
•

available GPRS and GSM networks.

Security
You can use various codes and locks to prevent unauthorized use of the
phone.
PIN Code
The PIN (Personal Identification Number) is the password provided
by your network operator. When PIN code authentication is
activated, it will prevent unauthorized use of the SIM card. You need
this password in order to use the SIM card.
If you enter the PIN incorrectly three times in a row, the SIM card
will be locked. You must now enter the PUK (Personal
Unblocking Key) for that SIM card in order to unlock it. Please
contact your network operator to obtain a PUK.
