When you say "app" am I correct that you want to watch BT sport on a mobile device like an Ipad?
If so then you open the app on your Ipad and enter the PIN there when prompted.
You can also download the app to watch on your computer
If this doesn't solve your problem then please press reply to expert rather than rating my service.
Does this apply to you please?
No, Sky Sports 1 and Sky Sports 2 channels from BT are currently only available with our BT Vision+ box. We're constantly looking to improve the service we offer, including looking at opportunities to bring more content to our customers.
