Would like access to BT sports mobile app at a special rate

[Crabstix2]

I bought a Ee pay as you go Sim from the pound shop. It's 5GB for 10GBP with 20GB extra for the first six months.

I would like access to BT sports app at a discounted rate.

1)What promos are there for this? 

2) Do I have to switch to monthly contracts to get BT Sports app access at a discount?

3) Can I switch to EE network using this sim and keep my old giffgaff number? If so, how?

I have inserted my sim into my phone. What do I do next?

Thanks
