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 
eectively 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 trac to 
handle additional calls).
Avoid using the phone at such 
times, or try again aer 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.

part of your service provider.
End the call and dial again.  
You may be switched to a
