I have a Verizon Galaxy S3. A few months ago I got a notification in my notification bar that I have a voicemail. It says "New voicemail (-1) Dial *86". I can't get rid of it, its been there for months. The notification has been there for so long, I can't even remember what happened to cause it to be there. When I dial *86 and enter my PIN, it says I have no voicemails. But I don't even use the Google voicemail app, I use Google Voice for voicemails. I'm rooted and I have the App Quarantine app. I put the Voicemail app in quarantine and rebooted, but the notification is still there! Does anyone have any ideas how I can get rid of the voicemail notification? And BTW, how could I have "-1" voicemails??
