Why isn't my iPhone group text including my Microsoft Phone?

Iphone group text not including Microsoft Phone

We have a group text thread that includes about 10 iPhones. I cannot add my son's Microsoft phone. I get this error: "‪+1 (000) 000-0000‬ is not registered with iMessage." How do I configure so he can be added to this thread? Thanks.

You cannot I don't believe. iPhones are their own evil ecosystem.

iMessage only works on iOS devices. You'll need to use regular SMS for people who have Windows Phones or Androids.

It sounds like your phone is using iMessage for group messages ( certain carriers put a limit on the amount of users that can be added to a group mms/sms). Your best bet would be to use GroupMe which supports every platform including users without the app.
