I have always had LTE on my iphone five. For some reason my brand new 6 plus will only pick up 4G. I was with a group of people with all different versions of iphones and I'm the only one with 4G. I called AT&T and the lady tried to tell me that LTE and 4G are the same thing and it didn't matter since there was no difference. I know that this definitely is not true. I just want to know if there is something actually wrong with my phone. I had to go through h*** and back to get this phone and the last thing I want to do is take it back. I have heard that apple doesn't even have any left to give people as replacements.
