My granddaughter has a new iTouch. I have an iPad non cellular.... She can I initiate a FaceTime call to me but can I initiate a FaceTime call to Her on my I pad
Yes you should be able to do that, ther is even a facetime app on the ipad where you should see her last calls so you directly call back.
Also if you've added her to your contacts, there is a facetime option in her contact card.
