Both my wife and I have the iPhone 5s. When our kids text us using imessage, sometimes we get the message, sometimes one of us gets it and the other does not, and sometimes one of us gets it and the other is delayed anywhere between 6-24 hours. This happens even when the two phones are docked right next to each other. I hope someone knows of a fix because I am dreading having to call Verizon. Thanks.
