I have had a several year history with Pay-As-You-Go DISH. Bought one of the early Dish-For-My-RV setups which included the Winegard Carryout and the receiver. In the beginning, NONE of the CS Reps knew what to do. I had to explain many times what the PAYG plan was. I was always connected to the "Loyalty" department where I usually got someone who knew how to handle my account.
With PAYG, you pay for a full month up front. The account is good for 30 days from that date. If I only use one week of that service, I call DISH and ask them to "Disconnect". I explain that I have an RV and we are now back from vacation. I used to have to prompt the Rep to transfer me to Loyalty (they are the only ones allowed to disconnect service), but lately I am transferred there readily as it seems the word is getting around. In the beginning, I found CS Reps that did not even know what an RV was.
The balance that is left remains on your credit until you use the service again. If you restart within the original 30 days, there is no additional charge. If you restart after the 30 days, you have to pay the difference to bring the account up to the 30 days again. In essence, you are replenishing your account for what you used the last time. Your account can stay for months with a partial credit and you can restart it at any time with no penalty. Due to circumstances, mine was almost a year and I was able to keep my credit. They did, however, think I'd left them and called to woo me back. I told them I never left and explained the RV thing and they marked my account accordingly.
I've used this many times and the only pain is them getting the receiver to come out of dormancy when I don't use it for several months. I have always been able to get it to work though.
