You might want to check the HBO Go app settings. Some apps have a default option to only work with wi-fi only. If so, just uncheck that to allow the 4 G too. ( I don't know if this is the case, just guessing).fblack_111 said:On the day the story broke that Sling TV was starting, I sent them an email asking some questions like: Would they have a Samsung Smart APP for Smart TV's, can you watch more than one stream at a time on different devices, why limit re-runs of shows to only 3 days, etc. After waiting three days I got an email back that said: "We have received your email and want to make sure we help with your request as soon as possible. Due to the overwhelming response to Sling TV, it may take us a few days to respond. If you need immediate assistance, please call us ...". I assume I will get an answer eventually. I also hope they expand their choices (even at extra cost) and let customers just pick and choose their channel lineup.
And one other slightly separate issue. I put HBO Go on my Tablet. It's fine via wi-fi in my home. Then I took my tablet outside and used it's 4g feature rather than wi-fi. The app said that it only works on wi-fi. I thought that was odd. And I am not sure it would work at say an airport using a public wi-fi. Or only your home TW wi-fi. I wonder how the Sling TV would work on portable devices outside the home.
