My initial thought was roughly the same -- I have wifi at home, at work, at the gym, at the coffee shop. The only time I go over 2GB in a month is if I turn off wifi for some reason and forget to turn it back on when I got to work/home.

But to your point, I also watch videos primarily on my laptop, not my phone. I also have a phone with plenty of storage so I can cache all my most listened to music, my audiobook, and latest podcasts.

I technically have unlimited data, albeit dropping down to 2G speeds after 2GB, but I almost ever hit that limit. The cost isn't a factor for me, since it's flat-rate. I know it is to some people, but it's the presence of wifi and my preference for watching videos on my laptop that keeps mobile data usage low.

Or there is no fixed connection available, so mobile télécoms aren’t worried about cannibalizing another department in their company by hitting the « ON » switch on cheap GBs.
