This morning I was thinking about setting up Visual Voicemail. I have a Nokia Lumia 920, and cellular data is disabled. I did that to save on expensive charges and I am connected to my WiFi network.
Then when I opened the Phone app and panned over to Voicemail, at the top it said: Can't connect to visual voicemail. I then tried to go to Internet Explorer and I could view Bing. Can't you make it so you can browse Visual Voicemail in WiFi?
So then I enabled Cellular Data on my phone and I could view Visual Voicemail. I then turned it off and it can't. Is there a way that I can use my data plan only for Visual Voicemail and nothing else?
if you have cell data turned on and your connected to wi-fi it will use wi-fi for whatever it can and will use cell data for what it needs to use it for such as multimedia messages and visual voicemail. this is how i have my phone setup and i dont use cell data unless its for something it has to be used for.
Visual Voicemail can only be delivered over the 4g connection. It cannot be downloaded over WiFi. You should know however that AT&T does NOT charge you any data charges for visual voicemail data when you are on the AT&T network.
