I have an iPhone 4s on Verizon Wireless, I switched to Verizon a little less than a year ago and have not yet gotten my voicemail to work. I call *86 and press # but have no clue what my mailbox number is. I have never set one up and I have talked to Verizon sporadically since the Summer and no one seems to be able to help. I have tried every number I can think of as the mailbox number but none of them work.
