a basement or near a tall building,
because wireless transmissions cannot
effectively reach it .
Move to a location where the
network signal can be properly
received .

(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 .

station for your service provider .
You can request a service area
map from your service provider .
