Do you download music, videos or television programmes to watch online? If so, great. However, it comes with a major cost. Most broadband packages have an inclusive monthly allowance of data to which you are limited. This tends to be around 1 to 5 gigabytes. Downloading music, software or videos eats up the allowance much faster; downloading a half-hour BBC programme from iPlayer will use around 300 megabytes. So some people will be busting their monthly allowance just by watching three TV programmes and face paying expensive charges for going beyond the limit. The solution? Shift to a broadband package that gives you a bigger allowance. O2 is currently charging £12.50 a month for a fast, unlimited broadband connection. And if you are already an O2 mobile user, you can get the package for just £7.50 a month. “Fair use” policies may apply.
