Q: How many people can you put in a single group message?
I've tried sixteen for my softball team and they get put into four different threads and it doesn't work. I also have two people without iPhones could that be the problem?
According to the following, a group message will be sent via iMessage only if all recipents have iMessage enabled. It also states that the maximum addressees for group messages sent via MMS may be restricted by your cellular provider: http://support.apple.com/kb/HT5760
