If you have a work email or school email, you type it in, and it will let you know if it is supported. I entered my old college email and it came up that I get 15% off my bill with Sprint...I'm still on the fence as to whether I wanna do it or not...But it definitely works. My mom uses it and gets 25% off her bill because she works with the state. Thought this would be useful to you niggiz!
