Lumia 850/1900 for AT&T

I can't get my voicemail notification to work. I am using the sim from my iPhone 4S and WP recognized Visual Voicemail and asked for my password but it just says Syncing and never shows anything and the normal notification doesn't work when a message is left. What about yours?
 
I have always used to old school voicemail so I haven't had any issues. You may need to have your carrier turn it off. Do you still have the iPhone if you do maybe put the sim back in it and turn off vvm if you can do that with an iPhone I'm not sure I never had one.
 
Not sure of the MS Store price but TELUS in Canada offers the Lumia for $529 CAD off contract and are offering $100 all their smartphones during the month of March. Not sure if it requires an activation, but it's worth looking into... All 3 of the major carriers in Canada use the 850/1900 bands for HSDPA+. Available in black, cyan and magenta. Check out telus.ca for info.
