I have recently been using Goog411 (800-GOOG-411) from my mobile phone rather than traditional 411 service… Why? Its free (not counting the use of airtime). You can either have the information sent via SMS to your handset or they will connect you to the merchant at no cost.
I have had great success with the voice recognition, and have only gotten one dead number when I used the service… A lot better than 800-Free-411 where the voice recognition often can’t figure out the name I am trying to look-up.
But the question is, how are they making it free? 800-Free-411 has you listen to several silly advertisements, but not Goog411…
