Metro PCS is promoting the S4 as a phone that connects to either the Metro towers or the T-Mobile towers depending on dominance. Been testing this beast of a phone in my home town where a LG phone previously connected to Metro's 4G network consistently, in solid fashion. The S4 either goes no data connection or a paltry "E" - which I assume is EV-DO and voice bars are 1 to none. T-Mobile in my neighborhood has always been slim pickens; Metro is and always has been the bomb (with various other phones...). In a neighboring town awash in T-Mobile 4G, this S4 works great. Looks to me that this phone isn't networking switching for best performance as advertised. Considering the price, that's a shame. Anyone else experiencing this type of network connection behavior? Or perhaps a setting fix?
