Can't get my Samsung Galaxy S5 Active to send group text. (Straight talk AT&T)

I've tried many different things to get me new phone to send group messages. I was finally able to send a group text to my sisters and mother. But I received them all individually so we weren't actually in a group...? What can I do to fix this problem? I've tried EVERYTHING!!! Please Help!!

I'm also unable to send/receive MMS or SMS pictures? I'm STUCK!

Welcome to Android Central! Is your mobile data on, and connected successfully to the web? Group texts are sent as MMS, so you need mobile data on (not just voice signal or wi-fi).
