Our take on the Samsung Galaxy S21 5G G991U 128GB - Fully Unlocked (Refurbished)

The Galaxy S21 5G is Samsung's 2021 flagship phone, now widely sold refurbished. It pairs a 6.2-inch 120Hz AMOLED screen with a Snapdragon 888, a triple camera led by a 64MP telephoto, and 8K video capture. It suits shoppers who want flagship camera and screen quality without paying new-flagship money. Against newer rivals it gives up battery life, charging speed and a memory card slot, and it ships without a charger. Owners praise the smooth display and zoom camera; common complaints are average battery endurance and a plastic back on this generation.

Questions and answers

Is the Galaxy S21 5G still worth buying?
Yes if you want a compact flagship camera and screen at a lower cost than newer models. Expect average battery life and a shorter remaining software support window.
Does it work with all US carriers?
The fully unlocked model works on AT&T, T-Mobile, Verizon and prepaid carriers like Cricket and Metro. Check that your carrier supports the phone's 5G bands.
What is in the box?
Typically just the phone and a USB-C cable. Samsung stopped including a charger and earbuds with this generation, so plan to supply your own.
How does it compare with the S21 Ultra?
The Ultra has a larger screen, a bigger battery and a second telephoto lens. The S21 is smaller, lighter and easier to use one-handed.
Does it have a microSD slot?
No. The S21 line dropped expandable storage, so the 128GB built-in capacity is all you get.
What does refurbished mean here?
The phone has been restored and tested to work, but cosmetic condition varies by seller. Check the seller's grading before buying.
