Problem
I cannot make or
answer calls.
My handset has
poor reception and
drops calls.
The screen says:
Data Calls Only.
I cannot hear
others on my
handset.
I cannot open my
inbox.
How do I see the
calls that I made or
received?
Solution
Make sure you have a network signal.
See "Network" on page 33. Avoid
electrical or radio interference, and
obstructions, such as bridges, car
parks, or tall buildings.
Your handset also may have the call
barring feature turned on. See "Using
Call Barring" on page 53.
Make sure the antenna is not bent or
damaged.
Also, make sure you have a network
signal. See "Network" on page 33.
Avoid any obstructions such as
bridges, car parks, or tall buildings.
You are in an area where the network
does not support voice calls. You can
make only data calls until you move to
an area where the network supports
voice calls.
While on a call, press the Volume key
on the left side of the handset. The
sound should get louder.
Before you can use messaging
services, you must set up the
accounts in the handset. See "Setting
up Messaging Accounts" on page 56.
To see the most recent calls you
dialled or received, open the call
history list. See "Viewing Call History"
on page 48.
