To get prepaid you MUST fail a credit check during the activation of your iPhone. The easiest way to do this is by entering all 9's as your social security number, you'll fail, and you can pick prepaid. It has a few plans, and it shows you all the plans and options, you pick one, pay before the next billing period, and get whichever features/ options you chose. All the plans come with unlimited data (i.e. Web, email, stocks blah blah blah) and a certain number of minutes. Every time you use some of your minutes you'll get a message telling you how much you just used and how much you have left. Simple and no hidden charges, taxes, or fees. You do need a debit card though. Only catch.
