I even don't know at the moment where mine is. I rarely use it, just when I'm on tour or something. It happens that I get a text and don't see it until a few days later.

I can live very good without one, just when I'm on the road I don't want to miss it. And on my way to work where I have to drive quite some time it gives me somehow the feeling of beeing safe. If my car brokes I can call an automobile club without searching for a phone.
