If you have moved your broadband provider from BT to EE then your EETV products associated with your BT broadband line (and billed by BT) will I believe have stopped. EE do provide the EETV product on their broadband which is based around a choice of Apple TV or the EETV Box Pro (if recording required) with EETV Box Minis as multiroom boxes.
So it looks like you have become an EE customer is that your understanding ?
If that is the case then you would need to establish a new EETV contract with EE.
Your current BT TV box may be yours to keep or a loan box (requiring return) depending upon the terms and conditions applicable at the time it was supplied.
