Weird situation happened to me while traveling for business last week. My LTE datawould NOT work in Nashville, TN. All week it showed I had 4G and the arrows were flashing transmit and receive but data would NOT work. I could not get on the internet, FB, or text unless I disabled LTE and only went CDMA. I flew through Philly and put LTE back on and data worked no problem. Any ideas why it just would not work in Nashville?
