Poor reception

your current location, for example,
in a basement or near a tall
building, because wireless
transmissions cannot effectively

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 can request a service
area map from your service
