His question does indeed make sense - Assuming a fairly generic setup, he will have an icon (Speedtouch) on his desktop to connect to the Internet. After double clicking this to connect, he will then have to double click the IE icon to open a browser window to use the Internet.
If your connection preferences are set to dial a connection when you attempt to access the Internet, you should simply be able to open IE and go to a webpage. If you are not already connected, it will either connect automatically or prompt you.
When I used one, it would connect automatically as soon as the device was detected so I didn't need to manually click on the modem icon.
