I'm posting this out of a month of frustration. I've had my iPhone 6 plus since the minute they were released and I've had no issues with it. Now, after iOS 8.3 and 8.4 my phone is basically useless. My calls are constantly being dropped, and I mean constantly...9 out of 10 calls. I cannot wait a video or even view a picture on Instagram. I live outside of Charlotte and work downtown and it doesn't matter where I am, the phone refuses to work and gets a poor signal.
I've tried resetting the phone and doing all of the software updates and at this point I'm at a loss. Is there anyone else out there with an idea of what's going on or living in the Charlotte, NC area and having similar issues? Please help! Thanks in advance.
