256GB iPhone 13 Pro Max

The Apple iPhone 13 Pro Max is a factory-new smartphone with 256GB of internal storage in the Sierra Blue finish. It arrives locked to the AT&T network and carries a Grade C cosmetic rating. This means the body may show dents, cracks, chips or scuffs, and the display may have scratches or dark spots. Functionality is unaffected by the cosmetic condition.

Buyers who accept cosmetic wear for a lower cost

This unit suits shoppers who prioritise storage capacity and the 6.7-inch Super Retina XDR OLED panel with 120Hz ProMotion over a flawless exterior. It is not for buyers who need an unlocked device for use on other carriers, nor for anyone who requires a pristine screen and chassis free of the noted dents, cracks, chips, scuffs, scratches or dark spots.

AT&T network lock

The single specification that decides compatibility is the carrier lock: this iPhone 13 Pro Max works only on the AT&T network unless officially unlocked by the carrier. Verify that your service plan and SIM or eSIM are compatible with AT&T before purchasing.

Questions about this item

How can I confirm the 120Hz ProMotion display is active after setup?

Open Settings, tap Display & Brightness, and verify ProMotion is set to 120Hz; the screen should feel noticeably smoother when scrolling.

What accessories are included with this AT&T-locked iPhone 13 Pro Max and what must I buy separately?

The box contains the handset and a USB-C to Lightning cable; you will need to purchase a power adapter and, if desired, a MagSafe charger separately.

Should I choose the 256GB Sierra Blue model or consider another storage option?

The 256GB capacity suits heavy photo, ProRes video and app use; select a higher tier only if you routinely fill that space.
