How am you getting Internet on my iPhone 4S without Wi-Fi?

So it says 3G on top, but I'm not on a contract or bill pay so how am I paying or getting this Internet?

I'm getting it as I have a contract, you would be better off asking how you are getting it.

I haven't had it for months!

Well it only mean that you are in a 3g area. So if you try the internet it will bring to you to your provider screen saying that you need to but a plan to access your internet.
