A sky digital viewing card is paired to a box via it's serial number. You can take the card out and place it in another box and it will work but you will not get access to premium channels such as movies and sports. I will point out this is not illegal activity and sky will allow you to do this they will even pair the card to the box for you if you ask them to! (sky will not pair your viewing card to different boxes every 5 mins though!)

However, you can take the original sky box that the card is paired to with you as long as you are not required to keep it connected to a working phone line that it was originally installed on.

As long as it's outside it's 12 months contract or if you paid sky the £25 opt out fee you can take the box anywhere in the uk as long as it's being used by the person who is the subscriber!

If you have multi room then you cannot remove any of the hardware from it's original installation place and all boxes must remain connected to the phone line they have been registered against!
