Everytime I miss a call, I get a text from Verizon that says "//VZWVVM:SYNC:ev=NM;id=170;c=1;t=v;s=phone#" Any idea what's going on and how to disable it? I'd like to have visual voicemail, but I think its a paid add on for my plan. I can't find a visual voicemail setting in the phone. Thanks in advance!
