I have a Google Pixel and recently found out that my voicemail isn't working. I honestly don't know if it's ever worked since I got this phone because it's so rare that I get a voicemail.
When someone tries to leave a voicemail it says "Enter mailbox number." When I try to call my own voicemail from my phone it says to enter my mailbox number. I enter my 10-digit phone number, but it says "Invalid mailbox number." I've tried to have visual voicemail turned on and off and it says the same thing. When I try calling customer service or asking in chat, it just gives me a link to set up voicemail, which takes me right back to where it says "Invalid mailbox number." How do I get past this?
