about the Binge On option: it still works last time I checked , but I haven't streamed in awhile so not still certain about that.
The last stream I did was 45 days ago, and ended up using the location's Internet because T-Mobile was being spotty. I was having issues with it at Pinburgh. Called support and they confirmed a tower was down. Got into a conversation about Pinball and streaming with the tech, and he was surprised Binge On worked for Twitch. He stated it was a partner they were looking into, but hadn't been made official.
I suspect the reason it works is because Amazon streaming is a partner, and Amazon owns Twitch. I'm guessing the streaming traffic looks the same to an ISP.
I have a month to month plan, and if it stops, I of course will be cancelling. I'd be weary about committing to a contract without Twitch being on the official list.
