I may be moving back to New Jersey in the coming months. My cousin and his wife, my sister, and I may be living together, and they want me to bring my Dish service if I do move in with them. I'm currently using a 722k for my living room and my bedroom. I also own a 625 that's been inactive for almost two years. My question is, would I be able to reactivate the 625 upon having the service set up at the new address, and would I have to get a new smart card?
