Our take on the Samsung Galaxy S21 Ultra 5G SM-G998U1 128GB Blue (US Model) - Factory Unlocked Cell Phone

The Galaxy S21 Ultra is Samsung's 2021 flagship, a large phone built around a 6.8-inch 120Hz AMOLED display, a 108MP main camera with two telephoto lenses and up to 10x optical zoom, and the Snapdragon 888 chip. It was the first Galaxy S to support the S Pen, sold separately, and it still holds up as a camera-first phone for people who want a big screen and long zoom reach. Against newer flagships it gives up some low-light photo polish and charging speed, but owners still rate the display, zoom and battery life highly. This is a factory-unlocked US model, so it works on major US carriers.
