On the top line of the screen, the status bar displays icons to show the phone's
current status. You might see the following icons:
Digital Mode means the phone is operating in CDMA digital mode. If this
icon isn't present, the phone is either in analog mode or there is no service.
Signal Strength shows current signal strength. The more lines you see, the
stronger the signal. When this icon appears, you can make and receive calls.
If the signal strength is very low, you may not be able to complete a call.
No Service means the phone is not receiving a signal from the system. You
cannot make or receive calls. Wait a little longer or move to an open area.

not appear.)

privacy (if available from your service provider).

black bars you see, the greater the charge.
