I upgraded to iPhone 6 from a galaxy s3 (which had no data issues) and now my data barely crawls (.20 Mbps down and .16 up). I have enabled voice and data LTE, network reset, restored, turned on airplane mode for 10 seconds, and even got a replacement phone yesterday, but it's still .20 MBPS. The phone says LTE with 4 of 5 bars. I know it can't be the service because my Samsung was blazing fast at the time I switched...I know it can't be the iPhone because this is the second one. When I received the original and the replacement iPhones, they were 8 point something iOS and I upgraded both to 9.0.2. My latest zip codes are 79329, 79404, 79424, and 79413 and it is the same inside or out, cloudy and sunny, etc.....always .20 MBPS. I'm not sure what setting, hardware, or software issue is happening, but something is up...there are too many threads like this on the Internet (and I've seen identical threads about att iphone 6's too). Also, my wife has an older iPhone 6 with att and hers runs at 30 MBPS, like the iPad I'm typing this on. But not saying att has better service because my Verizon Samsung was faster than that when I switched last Tuesday.
