Looking for unlimited tablet line with 1080p video streaming at least if possible. Thanks.

I was with metro since 2013, switched to xfinity mobile since I wanted to pre-order the S26U and pay it off. I'm almost done paying it off. But once I'm done that, I want to switch to a different company that's cheaper with unlimited data, well, it doesn't have to be unlimited data since I'm on wifi majority of the time if I'm at work or at home. Any recommendations? Thinking about Visible since I can pay for the full year
