The Galaxy S8 received rave reviews when it launched. The smaller Galaxy S8 has a 5.8-inch display, while the larger S8+ has a 6.2-inch display. Internally, the phones are rather similar, with the only main difference being the larger phone has a 3500mAh battery where the smaller one has only a 3000mAh battery. Being an unlocked phone, you can simply take your active SIM card and pop it in and be good to go. There's a whole lot of glass on this phone, so be sure to protect it with a nice case.
