My phone has bunches of capabilities that I don't use or pay for. But it fits my hand and I can use it for calls anywhere.
For instance, it has a built in camera that I don't use, because I normally have a real camera with me. A Canon S95. I found a Kodak belt-clip case for $14 it seems to be tailor made for.
Another non-use is E-mails and text messages. They can wait till I get home. You can't send those to a land line anyway.
If I want, I can surf the internet, but why? I am old enough to have to use a magnifying glass if I do. Not worth it.
Games? There are enough people around playing games with you already, don't need any on my phone too.
I got my cell phone for a cell phone and the reliable coverage the provider spent good money on and that is what I use it for.
Blizzards in North Dakota are a good reason for reliable cell phone coverage. Except for a few tornadoes, what passes for extreme weather in Kansas and Missouri is just normal stuff day to day in ND. For instance bitter cold in the weather forecast in Kansas City is +30°? Naa, add a 30 MPH wind and subtract 60°. Now that's bitter cold. And that is why I needed something with reliable coverage in the first place. When it gets like that, it's time to zip the jacket up.
