I have a couple of questions.1. Can we switch from Subscriber A to Subscriber B and continue to use the Dish & Set top box of Subscriber A (Of course, this implies 'install correctly' and get a new card/subscription of subscriber B)? I know this is being made mandatory (or is it already mandatory?) like for mobile numbers, but is it possible now and today?2. In case of a new connection, do we have to use whatever set top box & dish is being provided for a particular broadcaster? Can we use a third party set top box?
