1. Begin by attempting to make a connection using your preferred application. I dial using Networkx.
2. If this error comes, try to do either of the following below one at a time and testing if its all solved.
3. Disconnect the modem from your computer and reconnect it. Try to dial and see.
4. If the above fails, then disconnect, restart your computer and see what happens.
