It appears that a number of people maybe getting duped by receiver sales on Ebay. Always send a question to the seller asking if the receiver can be activated and if the person does own it and will take it off their account.
Did this several times over the past month and have received some "honest" replies......ie bought the unit at an auction do not know who the original owner is......smart card is built in......really do not know as I do not have a dish. There are very few legitimate Bell Tv sellers on Ebay and a number have now been reported. Personally I have purchased several receivers and they were fine. However did get one once from (after a lot of digging) a pawn shop which could not be activated. Remember if it is too good to be true then it probally is not.
