But it's also available at no cost for some people who already pay for HBO through a cable or online TV subscription, and for some AT&T subscribers.
Think of it as a free upgrade.
HBO Max also has offline downloads, so you can store movies to watch when you don't have a cellular or Wi-Fi connection -- that feature is not available in the regular HBO Go app, which is free for people who pay for HBO through a cable subscriber.
More than 70 cable networks and online TV services seem to have made deals with WarnerMedia and offer free access to HBO Max if you already pay for HBO, including AT&T, Verizon, Spectrum, Optimum, Disney's Hulu TV, Google's YouTube TV, Apple TV, Altice One, Comcast and more.
Here's how to see if you can get HBO Max through the HBO subscription you already pay for.
That's it. Now you're be logged in to HBO Max and can access the additional movies and TV shows it offers without having to pay a new HBO subscription.
Again, this doesn't apply to everyone. I am a Comcast subscriber, for example, and can't access it. But, since I also pay for HBO through Apple TV, I was able to use that log-in for access to HBO Max.
