I'm making a group chat, and everybody has an iPhone or iCloud. Even before I put the contacts with iCloud emails, I just put two iPhone numbers, and it turns into an MMS group chat. Then, on my friend's phone, she was getting messages, but nothing was sent to me. She also had an iMessage group chat and could add people, and I can't. What's wrong and how do I fix it?
