I at one point had no internet at home, and no phone, period. Nothing. I was cut off. For months. Because I couldn't afford it.
I would visit Starbucks to use their wifi several times a week. That was it. Then my mom gave me a prepaid flip phone for my birthday; any time I couldn't afford refill cards, I was cut off again.
Then I was able to get an "Obama phone," which is even simpler in design, but I don't have to pay for it (it should be called a "Reagan phone," who started the program, or a "Bush phone," who extended it to cell phones, and it's paid for with one of those fees at the bottom of phone bills, not income tax). So I regularly had a phone that didn't get cut off.
The only reason I have internet at home is because I am able to ride a hotspot now. When that hotspot goes down, I can't do anything about it, and am without internet for days again.
I haven't had a smartphone in years. I used to. They are expensive.
