performs abnormally, you can refer to the chart below. If your
particular problem cannot be resolved using the information in
the chart, contact the dealer where you purchased the phone.

The network signal is
too weak at your current
location, for example, in
a basement or near a tall
building, because wireless
transmissions cannot
effectively reach it.
The network is busy at the
Poor
current time (for example,
reception
during peak times, there
may be too much network
traffic to handle additional
calls).
You are too far away from
a base station for your
service provider.
TROUBLESHOOTING
