I think it is just a factor that limits the business.

I don't own a smartphone or even a dumbphone. At times I had two prepaid phones, one on the Verizon network, one on the AT&T network. Neither one worked at my house. Between the two prepaid phones I could sometimes talk on the phone while traveling, whether that means driving around Upstate NY or visiting big cities.

At one point I was about to put another $100 on my Tracfone for a year's service and realized I'd accumulated 4500 minutes.

Given that I don't talk on the phone much and that the coverage is poor in places where I go, I don't even have a cheap phone plan, never mind an expensive phone plan.

So in my case, U.S. carriers could increase their revenue if they improved their coverage.
