Samsung Galaxy S21 128 GB 5G Phantom Gray, A+ Grade, unlocked
A+ Stock Samsung Galaxy S21, Phantom Gray, 128 GB, 5G, unlocked: TG's top used grade, fully tested with little to no visible wear. Corporate buyers who issue compact 5G flagships to staff and marketplace sellers who need near-new units for photos choose this grade; gray is the color that fits any fleet.
Samsung's 2021 Galaxy S21 moved the base flagship to a flat 6.2-inch 120 Hz Dynamic AMOLED 2X screen, the Snapdragon 888, and a redesigned camera block holding 12 MP wide, 64 MP telephoto, and 12 MP ultra-wide sensors with 8K video. It carries 8 GB of RAM, 128 GB of storage, a 4,000 mAh battery with wireless charging, and IP68 protection, and it was updated through Android 14. As A+ Grade stock with little to no visible wear, TG Wireless places it with corporate and institutional buyers who want near-new handsets for staff, with marketplace sellers who need clean cosmetics, and with prepaid dealers selling top-grade recent Samsungs.

Condition: A+ Grade
A+ Grade is TG's top used grade: fully tested and working, with cosmetics a step above A Grade and little to no visible wear. 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 Galaxy S21 is a 5G phone with full 4G LTE and VoLTE, so the US 2G and 3G retirements do not affect it. Lock state is per listing; see the network status line in the table. Unlocked US units (SM-G991U) carry the band set for AT&T, T-Mobile, Verizon, and their prepaid brands, including sub-6 GHz and mmWave 5G. The listing does not state the model number, so confirm the variant, 5G provisioning, and VoLTE acceptance with the carrier before quoting volume activations.
Resale fit
- Prepaid and MVNO dealers whose customers want a 5G Samsung flagship at a used-market ticket.
- Corporate, institutional, and fleet buyers standardizing on one unlocked 5G model.
- Marketplace and storefront sellers who list graded units with consistent cosmetics.
- Refurbishers and repair shops that source working units for resale or parts.
