There are several variants of the Samsung Galaxy S3 device and one of them is US Cellular variant that comes with 4G LTE enabled and the rest of the specifications are usually same as its other variants. To remind you the specs, the phone boasts a 4.8″ inch screen with the resolution of 1280×720, Android Ice Cream Sandwich out of the box, 2GB RAM and a 1.5GHz processor.
