My current Android phone, a Google Pixel 6 (that rarely has the location service turned on), has a voicemail feature that I love. It converts voicemails to text automatically (as long as it can understand them) - plus, both a delete button and call-back button is right next to the text so it's about as convenient as it gets. Both my parents are 83 and neither have the eyesight or dexterity to create a text that would take them less than 30 minutes to compose, so this voicemail to text feature is beyond perfect.
I know this info doesn't help you, Blue, but looking at the Google Play store, I see that there are voicemail-to-text apps, so maybe you can use something other than what Verizon loaded on the phone.
My last phone was a Galaxy / Verizon combo and I remember switching the texting app from the default Verizon version to a much more basic Samsung version. I can't remember why I switched, but I do remember that it was worth the trouble.
