Thanks much for sticking with me. You're right, I should have done it from the web page link for "Voice Settings" (though in my defense, their Help is a bit misleading in calling this web page link the "Settings application").
My guess now is that this feature isn't available on Virgin Mobile. I tried last night and this morning, doing as it told me:
- clicking "Activate Google voicemail on this phone",
- dialing the * + number that appears in the popup.
Both times I get the call answered with this automated answer:
My Voice Settings page then changes the link to "Deactivate Google voicemail on this phone", as if the change took. But I get the same old ring-race behavior.
The same happens when I reverse the voicemail setting, i.e., Click on "Deactivate Google voicemail on this phone". I dial the number that appears in the popup and get the same recording, and the Voice Settings page changes to "Activate Google voicemail on this phone".
Another clue for non-support by Virgin is that the Google Voice popup for "Activate Google voicemail on this phone" defaults to Sprint, and the "Change carrier" drop-down doesn't offer Virgin Mobile as a choice.
Thanks again, I really appreciate your help on this. I'll keep on the lookout in case I've misinterpreted these clues or committed operator error (and maybe I'll try re-installing Google Voice), but it may just be that I've got a low-cost, no-frills carrier that doesn't support this "frill."
