The idea is, a total of three or four people share a subscription to NFL Gamepass. One person subscribes, and obtains a user id/password, and then shares it with the others. If two or more people sign on at the same time, the first person who signs on, will be signed off automatically; but I have to believe, if that happened repeatedly, the NFL would cancel your subscription, and no refund would be given. For that reason, it's vital for the people sharing the subscription to communicate with the others, via email preferably, to reserve a time when you want to access Gamepass, to ensure only one person is signed on at a time. Once you have the user id/password, you can use this anywhere there is an internet connection. So, for instance, the Giants were playing the Jaguars (my team) one year; a friend of mine was a Giants fan, and so we arranged to meet at The Pub a day or two after the game had been played. We carefully avoided the internet for the game results, and were able to watch the game on a large screen TV, just as if we were watching the game at home. The entertainment value of a game is spoiled, if you know the outcome before the game starts, is the idea.
A subscription is around $200 USD, or roughly, 6,000 Baht. If three people shared that, it would come to 2,000 Baht each. If four people shared, it would be 1,500 Baht each. In theory, you could have many more people sharing; there are plenty of hours in a week, after all. But, as a practical matter, everyone would want to watch around the same time, within a day or so of the game date; so to prevent conflict, three or four people is optimal. You can watch any game at any time, even watch games from years prior, 24/7, whenever you desire.
