If a broadband package is listed as ‘unlimited’, there are no restrictions on how much or how often you can use it. By contrast, a broadband deal with a specific data allowance will only let you use a limited amount of internet each month, and going over this limit could cost you.
The problem with a data allowance is that it is very hard to accurately calculate how much data you’ll need in a month. Any online activity, from downloading files to browsing websites and watching videos will add to your data usage and it is very hard to keep track of all your online activity.
Even worse, you often can’t tell how much data something will cost you until you’ve already used it.
Unlimited broadband avoids these stresses but you could end up spending more money than you really have to.
