without limits In the world of ISPs, "unlimited" does not mean you can be connected to the internet 24 hours a day, 7 days a week. That is called a "dedicated" account, and generally costs about $100 per month. Each ISP has its own definition of what "reaonsable" unlimited means - some base it on the number of hours per month, some on how long a session is, some require that you be at your computer when you are using it.
