3. Signal Strength Your phone operates on radio waves, and the quality of radio 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 phone’s display, which scroll as the strength of the signal increases and decreases. Increasing your phone’s signal may be easy. Try moving your phone slightly, or move towards a window if you’re calling from inside a building. No service If you’re 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 affiliates, emergency calls may be possible via other networks to their designated emergency number only (e.g. 911 or some other official emergency number). Your phone’s display will remain empty, but a ' will appear at the top of your screen. No other calls can be made or received. Also, see “To Make An Emergency Call” on page 10. 7

Your phone operates on radio waves, and the quality of
radio 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 phone±s display,
which scroll as the strength of the signal
increases and decreases.
Increasing your phone±s signal may be easy. Try
moving your phone slightly, or move towards a window if
you±re calling from inside a building.

When network service is unavailable
