After 6 months it's £5 a month http://shop.ee.co.uk/comingsoon/bt-sport-offer-register-your-interest
It's been a while since the BT Group acquired mobile network EE and now we're seeing the fruit of that alliance. All EE pay monthly customers, new and existing, will be able to access BT's sports channels for free for six months.
Access is through the BT Sport mobile app for phone and tablet. All of the channels are available to stream live through the application: BT Sport, BT Sport 2, BT Sport Europe and ESPN on BT Sport.
As long as you have a pay monthly handset, tablet or SIM only plan for iOS, Android or Windows you will be able to sign up for the free access. After six months, you can either cancel the subscription or carry on, paying £5 a month.
EE customers on pay monthly packages will be able to sign up to and use the BT Sport app for free from 27 July.
