I have the one plus 6t. The problem is this every time I turn of my device ONLY data does no work MMS phone calls work. Now the only way I can get the LTE to turn back on is to remove the sim and put it back in. However before i messed with the sim card I did check to see if mobile data was on and it was. I also turn on airplane mode and that was no aveil. Can someone please shede some light on this on going situation????
