I setup.my voicemail account with my pixel when I first received it. However, I just now noticed that I am unable to retrieve my voicemails. I had the basic voicemail setup and when I call; it'll state I have 0 voicemails. I know this is not true because I've asked friends to call my phone in order to leave a voicemail. I thought it was a glitch so I purchased the premium voicemail package and I was able to receive the welcome message. But I cannot retrieve any of my older ones. I am not quite sure what to do.
You said "when I call" - on my Pixel I don't call in to Voicemail, I use the visual voicemail (free version). Tap the phone icon as if you were going to make a call, then go to the Voicemail icon. (Starred contacts, then recent calls, then contacts, then voicemail across the top of the main screen) What happens then? Can you see messages? Listen to them?
So, someone calls you, they leave a voice message (do they get a generic greeting, or one you have recorded during voicemail setup?). Are you connected to the cellular network when you try to retrieve the message?
I have the generic greeting and I am connected to the cellular network when I retrieve the message. I am not 100% sure what is going on but I have called my own voicemail from a different phone but it never appeared on my phone. It's kinda annoying especially since I know people are leaving voicemails but I cannot retrieve them.
Have you verified the notification for the voicemail in the voicemail preferences?
When you call your number from another phone, have you left a message for testing purposes?
