I use it and it works great. On my Pixel 4XL, visual voicemail was included in the Google phone app. For some reason, the google phone app on the Samsung does not give the option for the Visual Voicemail. I noted the Samsung app after first starting up and setting up the phone when I took a serious look at all the Samsung apps offered and remembered it, so I went to it, opened it up and darn if there weren't three messages already there I failed to delete last week when using the Pixel.
It works good, so I just left it alone and moved it to the home screen for easy access.
Look in the icon circle full of Samsung Apps that loads just like two other icon circles; one with Google Apps, one with MS apps). Or you can always go to the apps under settings and review all the apps listed under Samsung. I do that since one of the first things I did (as stated earlier) is look at the Samsung apps and then I do deleting of apps such as Facebook Spotify, apps I will never use.
I'm on a unlocked S22U, connected to Tracfone (Verizon service MVNO).
