Verizon-locked Galaxy S21 5G
The Samsung Galaxy S21 5G model G991U is a new 128 GB smartphone locked to Verizon service. It ships in Phantom Violet with a 6.2 inch Dynamic AMOLED display at 2400 x 1080 resolution and a 120 Hz adaptive refresh rate. The Qualcomm Snapdragon 888 processor paired with 8 GB of RAM drives Android 12 under One UI.
Buyers needing an unlocked handset
This unit only activates on Verizon, so shoppers who plan to use another carrier or travel internationally with local SIMs should look elsewhere. The single Nano SIM slot and carrier lock prevent multi-network flexibility. Users who want expandable storage will also need a different device because no microSD slot is present.
64 MP telephoto camera with 10X zoom
The rear array includes a 64 megapixel telephoto lens capable of 10X zoom and 8K video capture, a spec that defines whether the phone meets a buyer's imaging needs. IP68 water resistance and Gorilla Glass Victus add durability for daily handling. A 4000 mAh battery supports the high-refresh display and 5G modem.

Questions about this item
Will the 4000 mAh battery need replacement after a couple of years?
The 4000 mAh battery is sealed inside the IP68-rated chassis; replacing it requires professional disassembly and is typically done once capacity drops below usable levels after several hundred charge cycles.
What limit appears first when the Snapdragon 888 runs at peak load for a long time?
Sustained heavy workloads cause thermal throttling before the 120 Hz display or 5G modem hit their own limits, so the processor reduces clock speeds to manage heat.
How warm and loud does the phone get during all-day 5G use?
The glass-and-metal body becomes noticeably warm during continuous 5G data sessions, but there are no moving parts so it stays completely silent.
