EE customers are to be able to stream BT Sport for free for six months following the purchase of EE by BT:

It says it's for mobiles and tablets only, presumably it will be possible to 'cast' the feed onto the TV??

No, cast is blocked for BT Mobile customers, I'd expect the same for EE.

I presume you can watch via any tablet on wi fi, as long as you have an ee pay monthly sim?
