My wife lost her Iphone 4. Got her a new 5s but the old voicemails are not coming up. She had saved some from her farther who passed away two years ago. When I bought her a new phone back then she was able to transfer or at least get the old voicemail from her fliup phone to the Iphone. Now they are not coming up. How do I retrieve old voice mails. They were NOT DELETED. Just not coming up on new phone.
