Ensure you have subscribed to a Caller Display Service and
that it is active. You can check this by noting if your phone
displays data regarding your caller's number when you
receive an incoming call.
This may be due to your handset being de-registered.
All you need to do is type Register and send it to 00000.
You will receive a confirmation message back. This
assumes that your Caller Display service is active and
working on your line.
Note: Messages sent to 00000 are not charged for.
