Harbor Mobile (T-Mobile authorized dealer) has by far the very best deal on TRULY unlimited talk, text and DATA. There is no cap on data and no throttling after hitting a threshold. You also get 3GB of HotSpot data. After taxes and fees it’s only $ 53 a month. I’d have it myself but am fortunate to be on a grandfathered T-Mobile business plan and get the same unlimited everything for $ 50 a month after taxes and fees.

You can stream all you want. I use it to stream NFL games on my Sunday Ticket app and NFL Game Rewind library of all games since 2009. One game can suck 2 to 3bg of data.
