Noticed some different behavior with my iPhone 6S when it came to call waiting. Even a different alert "tone" for call waiting. However I also noticed I have LTE during an active phone call. Previously I could not activate VoLTE because of my account being a corporate account. Now I can't even find the setting in the settings menu. Regardless it's working great! Anyone else notice this or have an relevant information on it? Is this something Verizon rolled out main stream or do you think it's something just to do with our account?
