    Green is SMS. It means either your iMessage is off, or the other person is not using an iPhone. Or they have their iMessage off. If your messages are not sending, your signal may be low. You can try Reset Network Settings.
    Reset Network Settings
    Settings>General>Reset>Tap Reset Network Settings. You may need to enter your wifi passcode back in afterwards.
