Problem  Solution 
I tried to place a call and 
heard an alternating 
high/low tone. 
Your call did not reach the wireless system. You 
may have dialled 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 send/receive calls. 
Make sure that you have a phone signal. See the 
“Signal Strength Indicator” item. 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 
(
 > 
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. 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 volume key on the left 
side of your phone. 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 inbox. 
Before you can use text or information services 
messages, you must set up the appropriate inbox. 
See “Setting Up the Text Message Inbox”. 
How do I see the calls I 
sent or received? 
To see the most recent calls you dialled or 
received, open the “Recent Calls” lists: 
 > 
Recent Calls
 
> 
Received Calls
 
or 
Dialled Calls
