LG G3 - 4.4.2 - Stop SMS converting to MMS
So what you need to do is; before you create the message, when you are at the screen where all of your text messages show up, tap the menu button in the to right of the screen. Then tap settings and go to multimedia message. Once there uncheck the box that says Group Messaging. This can only be done from the screen where you see all your other text messages and can create a new message. Not once you are in the text itself. Hope this helps.
