I just recently purchased and setup a Blu Life One X on Net10 using an AT&T sim. I'm using Google Hangouts as my default messenger app. When I'm involved in a group/MMS message chat, every message that I sent, I also receive. I called Net10 technical support and they told me that everything is "correct." and that's "normal." I never had this problem until I setup my new phone. Can anyone help me with this issue? Thank you.
