My first experience with Google Mobile SMS (Beta) occurred last week when my boyfriend and I needed a phone number for a restaurant to order take-out. Since I didn't have my Blackberry with me we didn't have internet access, so my boyfriend suggested we text message Google for help. It was amazing! All he had to do was text the name of the restaurant to Google from his cell, and in a matter of seconds the restaurant, its address and the number were sent back to us via text message.

When you use Google SMS, you're sending a specialized query to Google. This could be a query for a phone book listing, for the definition of a word, or for the square root of 7,569. Based on your query, Google determines what specific information you're looking for and automatically returns the top results.
For a majority of the United States, you text your search to 466453 ('GOOGLE') and on most devices and Google will text message the results back. Google Mobile SMS (Beta) is only supported with certain carriers in different countries. Check to see if your carrier supports Google Mobile SMS.
