Wholesale Samsung Galaxy S21 G991U 128GB Phantom Gray - C/D Stock (Unlocked)
Samsung's 5G Flagship Android Phone for Business, Government, and Education
The Samsung Galaxy S21 (G991U) in Phantom Gray with 128GB of internal storage delivers flagship-class Android performance to organizations that need dependable mobile hardware at wholesale pricing. Offered fully unlocked and in C/D Stock condition, this SKU is built for procurement teams that value predictable specifications, carrier freedom, and a proven device platform that has already served millions of enterprise deployments.
Every unit ships unlocked, allowing IT departments to provision devices on any compatible domestic or international network without carrier restrictions. This suits organizations that manage mixed-carrier fleets, rotate SIM profiles, or deploy across multiple regions. C/D Stock units are fully functional and tested but show more noticeable cosmetic wear such as visible scratches and surface blemishes; protective cases and screen protectors are recommended for daily field use. For buyers focused on operational value rather than showroom appearance, this grade offers one of the strongest cost-to-capability ratios in the current Android market.
This model is available in 1 of 1 channel: TodaysCloseout.com, giving distributors, integrators, and institutional buyers a single, reliable source for consistent inventory and repeatable bulk orders.
Design and Build Quality
The Galaxy S21 pairs an Armor Aluminum frame with a Gorilla Glass Victus front and a durable composite back, producing a resilient chassis suited to frequent handling in professional settings. At roughly 151.7 x 71.2 x 7.9 mm and about 169 grams, it is compact and comfortable for all-day one-handed use. The Phantom Gray finish presents a clean, professional appearance appropriate for client-facing roles, executive fleets, and public-sector environments, while the IP68 rating provides dust and water resistance for staff working in the field, on production floors, or in healthcare settings.
Display
The 6.2-inch Dynamic AMOLED 2X panel delivers FHD+ resolution with an adaptive refresh rate that scales up to 120Hz for smooth scrolling and responsive input. Peak brightness of approximately 1300 nits keeps content readable in bright conditions, an advantage for logistics, inspection, and outdoor service teams. High color accuracy and deep contrast make the display well suited to document review, dashboards, video conferencing, and detailed visual tasks across enterprise applications.
Performance and Intelligence
Powered by the Qualcomm Snapdragon 888 (5nm) processor paired with 8GB of RAM, the S21 handles demanding enterprise workloads, virtualization clients, and multi-app multitasking with ease. On-device AI acceleration supports real-time translation, voice input, image processing, and mobile productivity workflows. For organizations standardizing on a single Android platform, this level of sustained performance ensures the device remains capable well beyond its initial deployment cycle.
Camera System
The triple rear camera array combines a 12MP wide sensor, a 12MP ultra-wide, and a 64MP telephoto with 3x hybrid optic zoom, giving field teams a versatile tool for documentation, asset inspection, proof-of-delivery capture, and inventory logging. The 10MP front camera delivers crisp video for conferencing and remote collaboration, while advanced stabilization and low-light performance improve results in warehouses, clinics, and job sites where lighting is inconsistent.
Battery and Charging
A 4000mAh battery supports full-shift usage for most mobile workers, and 25W wired fast charging returns a substantial charge in a short window, minimizing device downtime between rotations. Support for 15W wireless charging and Wireless PowerShare adds deployment flexibility for shared charging stations and pooled-device programs, helping reduce accessory overhead across large fleets.
Connectivity and Enterprise Integration
The S21 supports high-speed 5G alongside Wi-Fi 6, Bluetooth 5.0, NFC, and USB-C, providing broad compatibility with modern enterprise infrastructure and mobile device management platforms. Its unlocked status allows seamless provisioning across carriers and regions, and it integrates cleanly with Samsung Knox for hardware-backed security, remote configuration, and policy enforcement, making it a strong fit for regulated and security-conscious organizations.
