When you refer to your cell phone, are you referring to it in terms of calling or for streaming? For calling, you'd need to have HughesNet Voice, as HN does not support wifi calling.
Satellite internet is not ideal for streaming due to the latency that's inherent in the satellite technology, and also to congestion (number of people in an area using the broadband at the same time). Satellite TV would be more appropriate if you want to watch shows and TV. Anyway, buffering and quality degradation tend to increase during peak times due to latency and congestion, neither of which can be helped.
