I was just wondering roughly how expensive a mobile phone or "cell phone" would be in the US.. and also do you have a pay as you go cell phone where you purchase cards and type in numbers to get credit?

Im on the road for 3 months. I have nobody really to call but I thought it may be good if I broke down or needed to get in touch with campgrounds/hostels etc.

I have a contracted phone in the UK and I would imagine it would work in America but as Im over for three months it would probably be a bit expensive. Ill check with my line provider anyway.
