4 devices on 1 Apple ID no have problems We have 2 iPad minis and 2 iPhones on the same Apple ID when I text my husband it goes to all 4 devices including mine twice. When anyone messages from the other 3 devices it goes to all 4 including my phone twice. When anyone tries to FaceTime  any of our devices it goes to all 4 devices. How can we get it to only go to one device ( the one we are sending the message to)?
Use different Apple IDs on each device. Using the same Apple ID will mean that the devices will be indistinguishable to FaceTime/iMessage/etc.
