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
making a call.
I cannot make/
answer calls. Make sure that you have a phone
signal (see the “Signal Strength
Indicator” item on page 24). 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
security menu
(
M > Settings > Security ). Also,
check to be sure your SIM card is
installed and working.
My phone has
poor reception
and drops
calls. Make sure that your antenna is
not bent or damaged.
Also, make sure you have a
phone signal (see the “Signal
Strength Indicator” item on
page 24). Stay clear of any
obstructions such as bridges,
parking garages, or tall buildings.
