At AT&T, if you trade in an eligible device, get an unlimited data plan and purchase the Razr on a monthly installment plan, you can get some truly huge discounts. Port your number and service over to AT&T, and get the Razr for half off and pay just $700. If you're an existing AT&T customer, add a line to get a $400 discount or upgrade your phone to get up to $300 off.
It's worth noting that AT&T is the only carrier that will carry the Liquid Mercury color Razr. It's the same color as the original Motorola Razr V3 from 2004.
