I'm changing to BT broadband tomorrow and will have a 5gb a month usage limit. I've always had unlimited broadband so have NO idea how much I use per month. Is there anywhere I can find out? cheers
BT will inform you if you exceed the limit, and dont charge you if you do it once. If you regularly exceed it they will start charging and suggest you change to another Option.
Just keep an eye on the size of downloads and you will have a rough idea.
