Yahoo Local users can now easily and quickly send phone numbers and addresses from the Yahoo! Local database to their cell phones or mobile devices as text (SMS) messages. The service is free but your phone provider may charge for text messages.
Each Yahoo! Local entry now contains a link labeled, "Send to Phone." Click the link and enter a phone number (U.S. only). Then, click "send." In a matter of seconds the name, address, and phone number of the Yahoo Local entry you've selected will be accessible on your phone or mobile device. Some phones even hyperlink phone numbers so don't even after enter the number. More info about this new service here.
The new Yahoo! Local mobile service is similar to another free service called Vazu that I've been using for several months. It works well. Vazu allows you to send text material from any web page to any phone around the world as a text message. Vazu also automatically recognizes phone numbers on web pages and you can even import, upload and send contacts from Outlook, Outlook Express, Apple Mail, or Ximian Evolution. Vazu requires a small download and only works with IE.
