I tried to place a
call and heard an
alternating high/
low tone.
Your call did not reach the
wireless system. You may have
dialed the number too soon after
turning the phone on. Wait until
the display shows the name of
your service provider before
placing a call.
I cannot send/
receive calls.
Make sure that you have a phone
signal (the signal strength
indicator should have at least 1
segment showing). Avoid
electrical or radio interference,
and obstructions such as bridges,
parking garages, or tall buildings.
Your phone also may have the
Call barring
feature turned on. If you
know the unlock code, you can
change this setting in the call
barring menu (
>
Settings
>
Call
features
>
Call barring
>
Cancel all
).
Also, check to be sure your SIM
card is installed and working.
