Our take on the Samsung Galaxy S21+ Plus 5G 128/256GB SM-G996U1 US Model Unlocked Cell Phones

The Galaxy S21+ is Samsung's 2021 large-screen flagship, sitting between the compact S21 and the S21 Ultra. It pairs a 6.7-inch 120Hz AMOLED display with a Snapdragon 888, a 4,500mAh battery and a triple rear camera led by a 12MP main sensor. It suits people who want a big, fast Android phone with a flat screen and good battery life without paying Ultra money. Against the S21 Ultra it gives up the 108MP camera and S Pen support; against newer S-series phones it lacks the brighter panels and longer software runway, but it remains quick and well built.

Questions and answers

Is the Galaxy S21+ still worth buying?
It remains a fast phone with a strong screen and camera for everyday use. It makes most sense if you want a large Samsung flagship and do not need the newest model.
How does it compare with the S21 Ultra?
The S21+ has a smaller, lower-resolution screen and a 12MP main camera instead of the Ultra's 108MP setup. The Ultra adds a periscope zoom and S Pen support; the S21+ is lighter and simpler.
Does it support 5G and dual SIM?
Yes, this US unlocked model supports 5G on major GSM carriers. Check carrier compatibility for your network before buying.
Is there a microSD card slot?
No. The S21+ has no microSD expansion, so pick the storage capacity you need at purchase.
What comes in the box?
Samsung ships the phone with a USB-C cable and SIM tool. There is no charger or earphones included.
How long does the battery last?
Most owners get a full day of mixed use from the 4,500mAh battery. Heavy gaming drains it faster and warms the phone.
