Anyone on here familiar with iMessage and shared Apple ID? My wife and daughter share id. She has iMessage on her macbook. She is able to switch between an email address and I guess the two phones linked to the ID. If she were to switch to my W's # would it send an alert to my W's phone stating such?
I know this only does iMessages but this info would be better than nothing.
Thanks for any help
