My brother got a voicemail that was delivered as a beta text. When he read it, it said:
Hi, Mike. Sorry I haven't talked to you. Just wanted to know how everything is going. I'll try again later. Dad
And of course our father died in September, 2015.....
He erased the beta mail.....so there you are. Some people think it is a fishing email.....but his account is in his real first name - Paul....his middle name is Michael....
So there you are.....I am thinking I may see if there is a way to retrieve the message, but I am not obsessed with doing so.
