Samsung Galaxy S6 G920A 32GB Black Sapphire 4G LTE, A Grade, GSM unlocked
Lightly used and fully tested, this Samsung Galaxy S6 G920A is the 32GB Black Sapphire 4G LTE listing, A Grade under TG's A2 sub-code and GSM Unlocked. The 32 GB black unit is the standard prepaid-counter configuration for the S6, and A Grade cosmetics let dealers sell it as a near-clean device rather than a budget beater.
The SM-G920A is AT&T's version of the 2015 Galaxy S6, the model that moved the Galaxy S line to a glass-and-metal body. It carries a 5.1-inch Quad HD Super AMOLED screen at 577 ppi, the 64-bit Exynos 7420 octa-core, 3 GB of RAM, a 16 MP f/1.9 camera with optical stabilization, a 5 MP front camera, a touch fingerprint reader, and Qi and PMA wireless charging, with a sealed 2,550 mAh battery and no microSD slot. The listing's data field gives LTE bands 1, 2, 3, 4, 5, 7, 8, 17, and 20. TG Wireless sells the G920A to prepaid dealers, marketplace resellers, exporters, and repair shops as a low-cost LTE Samsung with a premium build.

Condition: A Grade
A Grade (A-Stock) units are lightly used, fully tested, and working, and may show very minor nicks or scratches. Units are supplied as graded; ask your account manager about packaging (original box, accessories, or handset only) when you request a quote.
Network and compatibility
The G920A is an AT&T LTE build with VoLTE, sold here GSM unlocked; see the network status line in the table for the listing's lock state. Its listed LTE bands 1, 2, 3, 4, 5, 7, 8, 17, and 20 cover the main AT&T and T-Mobile frequencies and much of Europe. US carriers now require VoLTE for voice, since 3G closed in 2022 and T-Mobile's 2G GSM ended on August 3, 2026, and AT&T activates only approved devices, so confirm this model's standing with the carrier before buying for US activations.
Resale fit
- Prepaid and MVNO counters on GSM networks that still accept the model, as a glass-and-metal Samsung at an entry ticket.
- Marketplace and storefront resale of reconditioned and A Grade units sorted by color.
- Export to GSM markets where bands 1, 3, 7, 8, and 20 give LTE coverage and the S6 still sells.
- Repair shops stocking S6 displays and batteries.
