Understanding the Display Screen
The top line of your phone’s
display contains icons that
indicate network status, battery
power, signal strength,
connection type, and more. The
following list contains icons that
may appear in your display.
Display screen icons
Signal strength—Always appears when your phone is
on and indicates the current signal strength. More lines
indicate higher signal strength.
Service indicator—Indicates a call in progress. When
dialing a number, this icon flashes until the call connects.
No service indicator—Indicates your phone cannot find
a signal because you’re outside a service area. You
cannot make or receive calls. Wait for a signal or move
into an open area to try and find a signal. The no service
indicator always appears when you turn on your phone
and disappears once service is located.
Roam—Extended roaming indicator. Roaming occurs
when you use your phone outside your home area. While
roaming, a wireless system other than your Wireless
Provider's handles your call, so the service rate for the
call may be higher than those made within your home
area. Please refer to information from your Wireless
Provider on roaming rates.
New Message—Indicates that you’ve received a new
text, page, or web alert message. You’re also notified by a
visual and audible alert.
