Does anyone experience something similar to my short story below. Driving out of town (3 hour drive), my went from Tmobile LTE to ATT 4G (slowest 4G ever at .5mb down) for pretty much the rest of the way, when I got to a big city again, I had (what should have been Tmobile LTE) but my LTE never showed up (just full bars for text/voice, no data). Eventually I turned airplane mode on/off and LTE appeared. now on the way home when I left the Tmobile LTE area i had only ATT bars the whole way (no 4G or data once so ever), when I arrived in my area again same thing Tmobile but no LTE. Instead of switching airplane mode on/off again I just left it....Finally after a good 45 min. of being in Tmobile area it turned LTE on. 1st question, why did I have 4G (ATT) data on the way there and not back? 2nd question is this a fault in the phone or networks where it seems to get "locked" into no data service? maybe questions are related to each other?
