I'm pretty sure there is a thread for this but I couldn't find a clear answer. I'm on at&t and switched from an iphone and I have absolutely no idea how to set up my voicemail. Is there an app I need to install or something? I've pressed 1 and called it and it says it needs more information and asks for my voicemail box# but I have no idea what that is. I tried putting my phone number in but that didnt work.
