The Pixel 6 and Pixel 6 Pro are Google's latest smartphones. Both run Android 12, are powered by Google's first in-house processor, and have a fantastic camera. You can get the Pixel 6 for free when you trade-in your current smartphone and sign up for one of AT&T's unlimited plans, or $800 off of the Pixel 6 Pro if you meet the same requirements.
The catch for almost all promotions on any carrier is that the amount of the credit that's applied to your bill is based on the value of the phone you trade-in. Which, unfortunately, is something you'll need to visit with AT&T to figure out.
As for AT&T's unlimited plans, you'll need to sign up for one that's priced at $75 per month or higher.
