What is ‘unlimited Internet?’ How can it be unlimited?

The limited/unlimited internet refers to the gigabytes basically meaning you get an unlimited amount and that means you have more time you can watch movies or listen to music etc. "Unlimited" is not referred to that there are no limits on the internet as in what websites you can look at and so forth. "Unlimited" also generally means "a normal monthly amount of internet use per household"- if you start supplying your whole neighbourhood with internet because you are unlimited the internet provider would probably question what you are doing.
