So explain this. I have determined that I CAN get 4G at my desk, as long as I follow this procedure: Go outside, toggle LTE to CDMA to LTE, make sure I have an LTE signal. Turn on Pandora, and take my usual lap around the complex. Go back to my desk, and place in a specific spot on my desk and leave it unplugged. It will hold 4G the entire time. But if I move it elsewhere on my desk, or even plug it in, gone. Every time.
