Learn what happens when your phone loses its connection to the call control system.
Sometimes your phone can lose its connection to the call control system. When this connection is lost, your phone displays a message.
If you are on an active call when the connection is lost, the call continues. However, you do not have access to all normal phone functions because some functions require information from the call control system. Your softkeys might not work as you expect.
When the phone reconnects to the call control system, you'll be able to use your phone normally again.
