Check AT&T Upgrade Eligibility Via Text

I've been eying a coworker's Galaxy Note 3 as a replacement for my aging iPhone 4s. However, I couldn't justify spending $700 so I wanted to check my AT&T upgrade eligibility. I found out you can do this without logging into your AT&T account or talking to an account rep.

You can check other things too, like checking your AT&T data usage via text and checking your AT&T bill amount and due date via text.
