In SMS settings of whichever messaging app you use, there should be an option for "Group Messaging: Use MMS to send a single message when the are multiple recipients." Uncheck this box, and whenever you text a group, you are sending individual messages to every person.
When you unchecked this option in the newest releases of hangouts, you cannot send messages to more than one person. Maybe in other messaging apps it works. The discussion is about getting it to work in hangouts
