You can get a phone plan for $10/month (unlimited talk and text no internet though) and $25/month(unlimited talk, text and data) from Republic wireless. Only caveat is, the plan is limited to android and you have to buy the phone for $299.00 upfront.

That is a Sprint plan, they've been trying to wean people off the discounted rates, but many companies give fairly significant discounts. I think I'm on a 25% discount currently through my girlfriend's place of business.
