So I am in Bloomington MN walking through the Mall of America with my new SIII. Now mind you, I am not in any stores, just in open areas. Throughout the entire mall, I have little to NO reception. As I post this, I am sitting in my home in Bloomington with off and on 4G and at times no reception at all. This is by far the best phone I have had, minus the reception issue which is HUGE, so I hate to return it. But damn...........Any thoughts?
