I'm not always home, and my data on my iPhone at home is very high, but it's WiFi so no big issues. My workplace is huge, so we have about 120 routers or so, but even then, you're constantly signing in, plus, do I really want my work to know what I'm doing? Anyway, I'll download a movie or 2 a month on Netflix, to watch during lunch break. So maybe 700MB a month there (setting only uses about 350MB per 90 minutes). Listening to online music or podcasts, probably another MB/minute or so. If 1 hour a day 5x a week, that's 1.2GB per month. Watch a few youtube video's, a couple more GB's, then the standard stuff, browsing the web, checking email, etc, a couple more GB's. When I was with Freedom, usually I could keep it to 5GB or less per month, otherwise they slow you. Sometimes I'd have a week or a little more to go, and already burned through 5GB and would have to puchase their $10 5GB add-on (I was on the BTS Plan)....the most I hit was 8GB.
My last camping trip, we realized we didn't have a lot of music that everyone liked, which meant me downloading a couple stations from Apple, so that was like 1GB.
Your attitude though, reminds me of myself a few years ago -- when I asked myself "How can people use 100's of GB per month for home internet?". Then Netflix happened. Then everyone had a computer, smartphone, and updating these devices, quickly the 25GB plan I had was horrible, so I got 300GB -- eventually that was useless so now I'm unlimited.
I think it boils down to what you want your phone to do, and how available WiFi is, and the dependability of that WiFi.
If I was someone that rarely came close to 3 or 4GB there is absolutely no reason, and no way I would move to a more expensive service. I was paying $102+tax every 90 days for 12GB of service. You can't beat that, if 4GB is all you're using. However, I do have friends outside my province, and I'm a heavy user. I had hoped that Shaw's purchase of WIND would change things. And things are changing now. Freedom has iPhones with excellent plans to match. $5 more per month and I would be typing here with a brand new iPhone 8. Though Freedom's network still pales in comparison to the others, I think Rogers/Telus/Bell are feeling some pressure.
I'm still checking up with PM because I'd expect them to have some sort of matching plan, but so far no. I do think in a short time, Canadians will have more competative plans, and I do believe we'll see an end to subsidized phones shortly. So plans will be plans, and phones will be an add-on, so a $1200 phone will cost you an extra $50/month + taxes (and interest, if any).
