Once you sign up for the AT&T Unlimited Plan and acquire HBO, you have the network for as long as you have the plan itself.
As a result of AT&T’s new Unlimited Plan, users who sign up for the wireless provider’s unlimited data plan (which costs roughly $90 for a single line) will receive HBO as a bonus.
However, the primary difference in this instance seems to be the fact that there’s no confirmed deadline for the HBO package.
Promotions of this nature are obviously nothing new; only last month we reported on how folks who sign up for DirecTV Now will similarly receive a free year of HBO.
