Q10 won't send group messages

So im trying to message 2 numbers and be able to go back and forth with everyone.. when I put the numbers in to text, it sends me message but they get it separately and not in a group message where all 3 of us can have a convo.

I've tried making a group contact in my contacts and that does the same thing.

They both have iphones. Is there anything I am doing wrong?

I believe you are doing things correct. I've never had any luck with group text, and is the reason I talked the people I want to chat with, to install BBM. The group chat in BBM is easy for everyone to seem the replies. It doesn't cost anything for the iPhone users to download. Great for family, friends or group interests.
