First let me say, AT&T has most of the time been great. No problems. Very helpful. My iPhone 5 doesn't get get optimal signal on LTE, and the first rep I talked to was VERY helpful. I had to talk to another rep to help with the sim AND When I asked, "Is there any chance y'all might put a tower in my area?" She said, "AT&T does not guarantee signal. Read your contract." I got SO mad. I started abusing. I even looked her up on Facebook.
