Condition: A/B Grade mix
This lot is graded as a mix of A Grade (lightly used, very minor marks) and B Grade (used, visible nicks and/or scratches). All units are fully tested and working. Ask your account manager for the split before you order.
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.
