I had a standard basic Razr, and had full 4g coverage at work (near mexico boarder in San Diego).
Now with my S4 I have at best 3g, and as of this morning its constantly roaming to Mexico instead of connecting to VZW here. Whats going on? This is supposed to be a more advanced phone, so why can't I connect to 4g in the same place I could 2 months ago with an older phone??
