Visual Voicemail on iPhone 11 Pro not working


No matter what I do I cannot get my visual voicemail to set up on my new iPhone. I have tried every recommendation possible and still have to call into my voicemail and listen to the extensive prompts just to delete a voicemail that I knew was spam. It is terribly inconvenient and I haven’t had to use this process in probably 10 years.

the only option for my voicemail I’m offered is “call voicemail” I don’t want to do it this way  

I have tried resetting my network settings, Siri language is correct, device language is correct, I’m fully updated, have tried toggling airplane mode, tried only WiFi, tried only cellular data, I’ve tried everything. This is SO frustrating.
