Am I understanding this right? I've just moved from an iphone4 to an HTC One. Love the new phone, but really struggling with some of the integration with Android. The issue I'm seeing is that I want to use visual VM using the AT&T visual VM that comes with the phone but if I'm using wireless it tells me "Visual VM does not work with a Wi Fi connection. Turn mobile data on or call VM for messages". If I shut wireless off it works fine. This is crazy! If I'm at home on wireless and I see I have a new message - I cannot use the app unless I turn the wireless off on the phone - or hold the "1" key down to get VM's. I know Google Voice is an option, but I don't want everything running thru it with a different phone number, etc. Am I just using the AT&T wrong? If this is all that's available for handling Visual VM then I'm bummed. Really don't want to go back to my old iphone.
