In answer to your question, if you're in the UK, there's no charge for this. It'll simply come out of your inclusive minutes. If you have no minutes, then you are charged at the standard out of plan rate for listening to this (40p per minute).
It's available to all of our customer's so you can start using it right away as long as you've got minutes left!
