I switched my old iphone 5 to my husband's number, and I have an iphone 6 plus now. For some reason, whenever I try to call my husband, I get a recording that says the subscriber that I have dialed is not available or may have traveled outside the area. He is able to get other phone calls, but not from me. I have checked to see if I was blocked on his phone and I am not. I cannot text him either. I have reset both phones. What can I do?
