Menu, Settings, Call Settings, Voicemail Settings, edit your voicemail number to *86,,XXXX where the XXXX is your password. The commas are pauses.
I inputted my actual phone number instead of *86 with a couple commas and my password but this doesn't seem to work. I don't want to use *86 because I was told it uses my minutes vs. Dialing my number direct. Is there a way to input my password using my direct phone number?
