Voicemail notification not working

[Speed69]

I have an Iphone Xs Max and my Visual Voicemail is not working plus its not giving me any notifications about new voicemails i have. I have to constantly keep dialing 1 to check to see if i have any messages. I've tried resetting my iphone and my voicemail system but nothing seems to work. Also I'm on verizon Prepaid if that helps. This has also been going on for months.
