You can use a Sky TV subscription card from the UK in Spain so that you can watch all your Sky TV and British TV channels in Spain.
However, if you use a Sky card in a different Sky box, then for some Sky TV channels, like Sky Sports and Sky Movies, then you will be unable to watch these channels. You will get the “This is the wrong card for this set top box” error message on the screen.
Using our satellite receiver, you can now watch Sky Sports and Sky Movie channels in your holiday home, without the need for “pairing” the card with Sky TV.

* Update : Due to changes in security, Sky Sports, Sky Movies, and Sky HD channels are no longer available to watch on “non Sky” digibxoes
