Troubleshooting
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 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 (the signal strength 
indicator should have at least 1 
segment showing). Stay clear of 
any obstructions such as bridges, 
parking garages, or tall buildings.
I cannot hear 
others on my 
phone. 
While on a call, press the upper 
volume key. Your phone display 
should show the volume 
increasing.
Also, make sure that your phone’s 
earpiece is not blocked by its 
carrying case.
I cannot open 
my text 
message 
inbox. 
Before you can use text 
messages, you must set up the 
message inbox (see your Start 
Here guide).
How do I see 
the calls I sent 
or received?
 
To see the most recent calls you 
dialed or received:
M

Received Calls
 or
Dialed Calls
My phone will 
not send 
voicemail 
commands, 
passwords, or 
other codes.
 
You must send PIN codes and 
passwords as DTMF tones while 
on a call. You can set your 
phone’s DTMF tones to be 
Long
, 
Short
, or 
Off
. If you have trouble 
sending numbers, try changing 
the DTMF setting.

Problem Solution
My phone’s 
display is too 
dark. 
Use the 
Contrast
 feature to change 
the level of contrast in your display 
(see your Start Here guide).
You can also use the 
Backlight 
feature to change the length of 
time that the display backlight 
stays on (see your Start Here 
guide).
My battery 
didn’t last as 
long as I 
expected. 
What can I do 
to extend 
battery life?
 
Your battery’s performance is 
affected by charge time, feature 
use, temperature changes, 
backlight use, and other factors. 
For tips on extending battery life, 
see your Start Here guide.
I am unable to 
record a voice 
note, voice 
name, or voice 
shortcut
 
Try moving to a quieter location to 
make your voice recording. Hold 
the phone about 4 inches (10 
centimeters) from your mouth, 
and speak directly into the phone 
in a normal tone of voice.
My TTY device 
doesn’t work 
with my 
phone.
 
Your phone must be set to a TTY 
mode for the phone to detect your 
TTY device (see your Start Here 
guide).
I plugged the 
data cable into 
my phone but 
my phone did 
not beep. How 
do I know if 
the data cable 
is ready to go?
 
The beep indicates that you are 
set up correctly. If you did not hear 
a beep, make sure that both ends 
of the data cable are 
connected—the smaller end to 
your phone and the larger end to 
your computer.
Also, your computer may have 
deactivated the port to save 
power. Try opening an application 
that uses the port, like a fax or 
dial-up application, to 
automatically activate the port.
My phone 
beeped when I 
attached the 
data cable, but 
my data and 
fax 
applications 
do not work. 
Some wireless networks may not 
support data or fax transmission. 
If you are roaming on an 
unfamiliar network, this may be 
the case.
Also, remember that data and fax 
transmission usually requires a 
subscription. Call your service 
provider for more information.
