My husband and I started a new plan with Verizon yesterday and both got the iPhone 5. Everything is working fine except for the fact that we can't call each other. We can text each other and we can both call other people, but when we call each other both phones go straight to voicemail. We can FaceTime each other and we receive other phone calls just fine! Just no regular phone calls. Our phones are NOT on silent, the switches on the side are both black(not orange) and we don't have each others numbers blocked(that we know of). Help!
