Though I've only had the phone for a couple of days, everytime I attempt to use the visual voicemail, it locks up the phone. On a couple of occasions, after 5 minutes or so, it unlocks. On three occasions, I've had to take the battery out to reset it.
I figured I would explore the knowledge base before I contacted Verizon to remove visual voicemail from my service. Right now, it's unusable.
