Available List The phone will list all the available networks so that you can manually choose the preferred one. Not all networks listed will necessarily be available for use. If you require further information, contact your network operator. Band Setting Allows you to set an appropriate band in the GSM network system. 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. 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. 88 Menus
