Galaxy s3 group messaging?

I hate to make a thread about this but I have been trying for quite some time to be able to group message with people on my s3 to no avail. I have downloaded go sms and have it set to mms group message but when I sent out the message to a group of people I still receive messages as individual messages from each person. This wouldnt be so bad but I can't read any of the messages that get send back. All the people in the group message are on iphones except me. They are mms messages but dont show anything if that makes sense. please help I am desperate.
