I use Boost Mobile,it's still running on the TMobile network as far as I know,the phone plan is suppose to be unlimited but around the time they closed on the TMobile Sprint merger I started seeing that speeds could be throttled after 35 gigs.I also have 30 gigs of hotspot with that too and with that much data I usually have enough data to steam a few hours of of video per month,some months I could probably watch 5 or 6 movies but if I'm casting them to TV I'm using data from the phone and hotspot,the Chromecast works off the hotspot too.
