Chris, I'm not sure why, but we are able to get SMS text messages without wifi or data with the Imessage button enabled. I actually tried to disabling the imessage to see if that solved the problem before connecting tech support, disabling imessage had no effect.
The problem which was implemented by tech support lied in the send and receive tray under the imessage button. You have to place a check mark next to your phone and your apple id. I also enabled the send text as a SMS if imessage is unavailable, along with the MMS button as well. The articles referred to in my last response were very helpful.
Tech support did also suggest contacting carrier as well if i'm still having problem. As of right this moment the SMS text are going thru. I love my iphone and appreciate your support. Again thank you and have a great day. JM
