The Verizon Voice Mail comparison chart lists Basic Visual Voice Mail as "Included" and supported on Windows Phone, so how do I activate it on my 822 without subscribing to the $2.99/Month service?
Activate it, then cancel the subscription or don't opt in when the month is over.
I don't think there is a free Visual Voicemail for WP phones. Basic voicemail is free, but the version iPhone users get for free is not available on WP.
