Connection
Allows you to set whether the phone will search for a GPRS network
when it is turned on.
• GPRS & GSM: When it is turned on, the phone will search for
available GPRS and GSM networks.
• GSM Only: When it is turned on, the phone will search only for a
GSM network.
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.
• PIN1 Code: Used to activate, deactivate or change the PIN1 Code.
To change the PIN1 Code, select Set Status and set to On. Enter
PIN1.
• PIN2 Code: Used to change the PIN2 code. The procedure is the
same as for the PIN1 Code.
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.
