The issue of download limits is a hot topic at the moment with many internet service providers claiming to offer unlimited download allowances that are in fact subject to fair usage policies, which means you will be charged for going over and above that limit.
Other providers such as Pipex have recently introduced more transparent broadband packages, meaning users pay in proportion to how much they download or what they need, and can choose to pay a top up fee should they need to go over their normal monthly limit.
