I have a Vodaphone UK card. It is now every 90 days you have to have activity. Sending a SMS will do the trick. You have to have a UK address to use in the address area. At least I had to be in the UK to get this done. I had to call CS to get my credit card regestered. Online regester didn't seem to work from the states. Now I am online with a Americian credt card. I can top up anytime.
I got my sim from
www.freedom-mobiles.co.uk/ they shipped it to me in the states with no problem. I hope this helps.
