How much does an at&t iphone bill cost a month?

My mom said I might get an iPhone but it depends on how much it costs a month

My friend has an iPhone on att and he told me a while ago that he just put his sim card into the phone and paid the same price each month, but it's the same plan, so he didn't have internet on it. I'm not sure if this has changed, but it's definitely something to consider. You also might want to just check att's website.
