Just a quick bit here...

Imagine your out on the road, and you need to get a phone number. As you come to the realization that you do not have it, and have no other way to get it...you cringe thinking about the $1.50 - $2.50 that your wireless carrier is going to charge you for the call.

there is another alternative...

As long as your phone has text messaging capabilities, you can send a text to 46645 or (Googl).

For example, if you were meeting someone at Boston Billiards and wanted to call ahead to reserve a table, you would simply text: "Boston Billiards Warwick, RI" and send to 46645.
This would return the phone number and any other information you didn't already enter that is available. It will often return multiple results depending on the query.

While many of us carry PDA's and can access the mobile web, it is often still much faster to simply text 46645. And it definitly beats paying your carrier $3 every time you leave a phone number on your desk before you leave the office...lol
