My first home internet connection was my mum and dad's portable hotspots on their phones in around 2012 (when I got my first Android enabled device), however that wasn't a consistant connection, (my video consumption on it, and my phones until I got a modern smartphone, and even past then mostly consisted of Tubidy and Vuclip .3gp files),
I later got my first consistant internet connection in 2014 (after taking about a solid month to get set up cause of our shitty ISP at the time)
