FaceTime Issues
I have an old iPhone 4 that I use to FaceTime my friends, and with certain people, the whole time we're on a FaceTime call, it says "Poor Connection." I don't understand why it only does this with certain people. I have tried to turn off "Your Number" on "Send & Receive" and it will not let me uncheck that option. If I go under FaceTime or iMessage, it says "Waiting for Activation," and I assume it is talking about a phone number, but I no longer have access to the phone number or the carrier that the iPhone was originally under. How do I get around this issue on my own?
iPhone 4, iOS 7.1.2
