I have an iPhone 5S and a replacement phone is being sent to me via asurion insurance, however, I'm really concerned about a voicemail on my old phone not being transferred. I've backed up my iphone several times to my computer since receiving the voicemail but I've heard only some will transfer ??? Can anyone tell me if there is a way to recover it? Do I need to SIM card from my damaged (due to water) phone ?? I'm nervous about returning the old phone until I'm sure I recover this voicemail. Please help! this voicemail is a message from my father who recently passed away and I will be devistated if I can't retrieve it some how.
