Just so you understand how satellite internet works:
1. Netflix, as with all streaming services, is a very data-intensive activity - lots and lots of pings and data to a streaming server. Satellite internet is a very laggy internet: It takes over 500mS for each byte to go from your house to the terrestrial internet on the West Coast, then to the intended destination on the internet, and back. When you put both together you have pure chaos. If you're trying to stream anything on your TV, everythng else in your home will now be competing for available bandwidth. In reality, everyone on the satellite BEAM you'e also on will be competing for bandwidth, because you're loading down satellite resources for everyone.
2. When you buy tokens or increase your plan you're not buyng more speed, you're adding more data to your plan. Unless of course you already exceeded your data plan and were being throttled, then you'd get a speed increase until you exceeded the new data threshold.
