I am in mainland Europe and I want to buy a Sky digibox so that I can get the freeview British TV channels. I have never had Sky before but I'm thinking of buying a digibox when I return to the UK for a holiday. What is involved in buying one? Do I have to give any personal details or sign up for anything? I know that I can get UK TV from abroad because friends of ours have a Sky box and can watch UK TV. Thanks in advance.
