Troubleshooting
If you encounter problems while using the phone, or if it 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.
Problem Possible causes Possible solution
Poor reception
The network signal is too
weak at your current location,
for example, in a basement or
near a tall building, because
wireless transmissions can
not effectively reach it.
Move to a location
where the network
signal can be properly
received.
The network is busy at the
current time (for example,
during peak times, there may
be too much network traffic
to handle additional calls).
Avoid using the phone
at such times, or try
again after waiting a
short time.
You are too far away from a
base station for your service
provider. You can request a
service area map from
your service provider.
