This phone has Exynos NOT snapdragon. It is an international version and does not work with my straighttalk SIM card. First, it doesn't connect to my mobile data, I had to add an Access Point Name so that the data would work. Second, the calls will not work unless the "wifi calling" is on. Plus, even when turned on, the calls hang up randomly, sometimes wont even ring, and 70% of the time I try to call someone, a box shows up that says "Not registered on network". I also can't send pictures AT ALL, and my texts randomly won't send.
