I have my service address listed listed at my hunting cabin rather than my primary residence as at the hunting cabin it is in the same DMA but qualifies for all distants. Didn't really see a point in changin it since I do use Directv at the hunting cabin for a couple of week a year. I got a new HDTV and I want to get the new 5lnb dish installed at my primary billing address rather than the service address. Can I do this? Will the installer call Directv and have my service address changed?
