iOS9 on iPhone6 isn't delivering my text replies to group messages as iMessage or SMS. Help!
I have an AT&T iPhone6 with the latest software update (iOS9.2) and my text replies to Group
Message is not deliverable as an iMessage or SMS. I've checked my settings for Messages and reset and also have the SMS button toggled to on. Is this an operating system upgrade issue or AT&T issue, especially since others in the Group Message are with Verizon. this has been going on ever since the iOS8 update. I appreciate anyone's insight on this problem. I haven problems texting/replying when it goes to single cell numbers, but it's a huge problem in Group Messages.
Thanks!
iPhone 6, iOS 9.0.2, iMessage
