I have switched from the iphone 4s to the iphone 6. on my iphone 4s my voicemail was setup and working just fine. now when i press the voicemail button it directly calls *86. it says "welcome to the message management system. enter the number of the person whom you wish to leave a message. if you want to access your own mailbox press pound." when i press pound it says "please enter your mailbox number". the mailbox number is not my phone number nor is it the password to access my voicemail. i have already had my password changed by the verizon support people by calling *611, and still i am unable to access my voicemail. how do i get my mailbox number or if i am unable to do that how can i delete my voicemail and re-setup my voicemail from scratch?
