No visual voicemail on iPhone 17 Verizon V1 eSim?

I upgraded from an old iPhone to an iPhone 17 and due to eSim had to switch from Ting Tmobile to Ting Verizon. Everything worked great on my old iPhone.

I have yet to be able to set up visual voicemail because the default Phone app won’t let me continue after setting a password. Searching this sub shows people have issues, but can get issues resolved with support. Ting chat support claims that visual voicemail is not available on my device and I need to download a 3rd party app. Is this really not possible?
