Apologies if this has already been addressed somewhere else. Since activating my 6+ I've had a couple people tell me they can't reach me via iMessage or FaceTime to my cell number, only to my email. Under Settings > Send & Receive for both my email is selected as the option; my number is listed but is greyed out / not selectable. Both of these people were using iPhones, though I don't know which version of iOS. I have had another person text me from an iPhone (again, I don't know which iOS version) with no difficulty, and I've also received texts from a non-Apple user with no issue. This leads me to believe this is an iOS issue as opposed to a carrier (Verizon in my case) issue, as I've also had no trouble making or receiving calls. So I'm just curious if anyone has encountered this and knows what the solution is.
