You can still recieve Sky subscription channels (assuming you want to). As long as you still have your old card, which you should, you can ring up sky customer services and just telll them to turn it back on at the package you require. The person living at the address the card is registered to will have strange bill arriving but that should not be much of a problem

Important tip though: DONT PLUG THE BOX INTO THE PHONELINE -
EVER :excl:
If you do, it WILL successfully dial the UK who will then immediatly know you are not in the UK and lock out the card.
Also, Beeb 1 and 2 can be ropey due to the restricted footprint they broadcast on, the rest of the channels hould be fine though
