Visual voicemail

Yes, I did indeed read what you posted. Since your screenshot did not show what was listed under "settings," I was just curious if the option for visual voicemail was listed there like it is on mine, or if the options under settings vary by carrier. When I set up visual voicemail, I had to specifically choose that option under settings.
Gotcha.. my apologies, I didn't consider the fact that the settings may be different with different carriers. I'm on at&t.
 
I get an error when I turn on Visual Voicemail. I have set a voicemail password with my carrier and it still does not work.There isn't a tab displayed called "Visual Voicemail" in the list. I only see "Speed dial; and History" as tabs. I am with Platinum Tel which uses the T-Mobile network, and it is a pay as you go account.
They have us use their APN(s) and not T-mobile's so I'm not sure if that matters. They have said that some functions won't work with Windows Phones on their network like SMS.
