EE and BT Bundles With A Sport TV Deal?

GSP

I wonder if I am getting the best deal out of these.

Our household has 3 mobiles, each with their own contract under EE costing roughly £100 month. 

For our landline and broadband we have BT Halo where our direct debit costs £52.50 a month. We make sure we don’t use any extra minutes for calls, so these cost nothing (well they do as they are in the package).

So in all we are spending £150 a month.

I would like to watch sport on TV, so would pay a subscription, but am I missing a trick here with my current packages?

Could anyone suggest a way I could watch sport, without reining back on the 3 mobiles and landline broadband? Our landline does come in useful from time to time.

Thanks
