I'm trying to use group texting with 20 people. I believe that the message goes out to everyone, but when I get replies, they come from individuals or a random assortment of people from the original group text (with a new new group/individual message being started). This gets VERY confusing. How do I get everyone to reply to the same 20 people in the original message and stay in the same conversation/thread? Does having different phone carriers matter? Does having different phones matter? Thanks for the help.
