3. Signal Strength
Your phone operates on radio waves, and the quality of ra-
dio reception depends entirely on the strength of the radio
signal in your area.
Because the radio coverage is maintained by a wireless
network, the quality of calls on a wireless phone depends
on the strength of the wireless radio signal.
The stronger the radio signal, the better the call
quality. A strong signal is indicated by the signal
indicators on the left side of your phones dis-
play, which scroll as the strength of the signal
increases and decreases.
Increasing your phones signal may be easy. Try
moving your phone slightly, or move towards a
window if youre calling from inside a building.
No service
If youre outside the wireless service
area,
12 6(59,&( will display on
your phone. No calls can be made or
received, including emergency calls.
Unavailable service
When network service is unavailable
from your service provider or its affili-
ates, emergency calls may be possible
via other networks to their designated
emergency number only (e.g. 911 or
some other official emergency
number).
Your phones display will remain empty, but a
'will appear
at the top of your screen. No other calls can be made or
received.
