Google voice used to work fine, but I've found increasingly a number of the more "serious" institutions like banks have been rejecting VoIP numbers like Google Voice occasionally. If I can recall correctly I also believe that many of the chat applications reject numbers that are not tied directly to a SIM as well. I have used my GV since it was still invite only and have had to give out my real number increasingly often.
