Twistedpoet: The dialer program is the little program that you have besides your browser, that you need to connect to your provider. In its setup you have the possibility to edit a timeout time that will count down as long as you are online but have no data movements (like during writing a text). If the time is off without further data movement, the modem disconnects automatically. Perhaps it is also possible to edit the same timeout time in the browser setup.
