Line Security

If your phone displays

Line Not Secure

while you are on a call,

your phone has detected another device monitoring the call.

This message does not appear when caller ID, call cost, or other

information fills the display.

Locking the SIM Card

Your PIN (Personal Identification 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. Contact

your service provider for your SIM card PIN code.

Note:

You can also activate your

PIN2

code, to protect secure

applications such as Fixed Dial.
