The speed is megabits per second—mbps. 75 terabytes a month is not the speed, but how much data you use in total and a limit on what you use before being charged extra.
75 terabytes a month equals around 220 mbps depending on what you’re doing.
Duh...
Why even offer satellite if the speed sucks. Raw speed is a given, latency and limits are the issue.
Streaming and Gaming is where speed really counts. Gaming is out because of latency, so streaming is all that’s left. Most streaming can adapt to sub-par speed to some degree.
If you are mostly using your connection for work you will probably be ok, just watching it for entertainment ( latency/limits) may be another issue.
