Are you looking for a BT Sport Day Pass to watch BT Sport channels online or via freeview? Despite obvious demand for such a product, BT don't offer a Day Pass (similar to NOW on Sky) that allows you to watch one-off matches or 24 hour access without a contract.
They do have a BT Sport App which allows you to watch BT Sport 1, BT Sport 2 and BT Sport 3 online or via your smartphone, but you have to sign up to a BT Broadband package or their BT Vision TV subscription in order to use access it. You can get this BT Sport app for £4.50 per month on top of your broadband purchase.
Further decline in BT Sport subscriptions and viewing figures will almost inevitably result in the introduction in a BT Sport Day Pass for fans who want on-demand access to live football - until then, you can subscribe to BT Sport on your Sky subscription for £20 per month.
