Coming from a perspective of metered data or throttling at a certain point if you have a UD plan that throttles I can get your point.
Most of my data is on WiFi, but that's not because I choose to use WiFi. It's because Sprint's coverage and speeds suck now. But that was not always the case.
I didn't have to take to WiFi until September 2012. For three and a half years we never had any issues on 3G and despite having WiFi at home and other places we stayed on cellular data.
Right now I pay Sprint $211 a month to use the WiFi I have at home that I ALREADY pay Cox $232 for. I'm not getting what I am paying for.
If I solely used WiFi everywhere and turned off cellular so there was no data use at all when off WiFi then I'd be paying Sprint that much money for what now? Phone calls?
No, I'm paying Sprint for unlimited data (they take $20 a month in premium data fees whether I use data or not anyway), not for the use of paid or free WiFi (such as at Starbucks or work).
The ironic thing about this situation (and one I sympathize with) is that now I use a lot of WiFi because with AT&T I have limited data, and when I was on T-Mo I used a lot of WiFi because I kept losing signal. Sure in a perfect world I'd have T-Mo's data plans with AT&T speeds and coverage, but that ain't the world we live in.
That said, I have no idea what in the holy hell you're talking about at the end. Why are you paying $211 to Sprint for unlimited data? 20GB for four lines is $100/mo. The heck are you doing with your plan? $20 a month in premium data fees? Why are you paying for that?
