Just got Visible service on an Iphone 12 and trying to setup voicemail. When I enter the phone security passcode or any other series of numbers it gets rejected. Can anyone explain how to setup voicemail please. Thanks in advance.
I had the same issue. Did a text with support and they reset Visual Voice Mail. This was for my iPhone 11.
Chat support is able to reset your voicemail. Please contact them to have the issues resolved quickly.
