Does 'Speedify' really work?

I was on speedtest and saw this on the side, and wanted to know what you thought about it. Basically, I think that it combines your 4G from your phone and then the actual connection coming through your modem, resulting in your internet speed magically being doubled. It advertises that it's a way to get past ISP throttling, and uses Netflix as a very specific example.

TL;DR: Will this get you past internet throttling?

you should just look into a vpn

It could get you past ISP throttling just by using the other connection, but you'll burn all your data for the month in a matter of hours
