Samsung Galaxy S9 Black 64 GB AT&T Locked, B Grade
AT&T Locked Samsung Galaxy S9 handsets in Black, 64 GB, graded B Stock: fully working, tested units with visible scratches or scuffs on the screen or body. Being locked, they activate on AT&T and AT&T-network prepaid brands, which is where dealers place them as a low-cost Snapdragon 845 Samsung with a Dual Aperture camera and a headphone jack.
The 2018 Galaxy S9 kept the S8's 5.8-inch Quad HD+ Infinity Display and glass body but fixed its weak points: the fingerprint reader moved below the camera, stereo speakers tuned by AKG arrived, and the 12 MP camera gained a mechanical Dual Aperture that switches between f/1.5 and f/2.4, plus 960 fps super slow-motion. The US version runs the Snapdragon 845 with 4 GB of RAM, 64 GB of storage, a microSD slot, IP68 water resistance, a headphone jack, and a 3,000 mAh battery with fast wireless charging. This listing is an AT&T locked unit graded B stock, with the carrier's full LTE band list in the source fields.

Condition: B Grade
B Grade (B-Stock) units are used, fully tested, and working, with visible nicks and/or scratches on the body or screen edges. They suit value retail and refurbishment channels where cosmetics are secondary to a tested, working unit.
Network and compatibility
The AT&T Galaxy S9 is a 4G LTE phone with AT&T VoLTE, so the 2022 US 3G retirement and T-Mobile's 2G shutdown on August 3, 2026 do not affect it, and it remains on AT&T's accepted-device list as of this writing. This lot is AT&T Locked; see the network status line in the table. It activates on AT&T and AT&T-network prepaid brands only unless unlocked, and the source band list includes bands 14 and 66.
