I've been using this on an occasional basis for several months now -- it's really helped me out a few times. Once was waiting for a hotel shuttle to pick me up from a client site, and it was taking forever for them to show up. I'd forgotten to print out a copy of my itinerary info, so I had nothing on me with the phone number. Used Google SMS to get it so I could call the hotel and confirm that they hadn't forgotten about me, and were on the way (I'd had three cabs offer me rides, so if they weren't going to get there soon I wanted to just grab the next cab). I could've called 411, but 12 cents for the SMS messages is cheaper than the $1.50 or whatever I get dinged for directory assistance calls, plus I've got a message on my phone I can save for later reference. I've also used it a couple of times to find out if there was a location of a particular store near where I was -- send a message with "<storename> Bridgewater, NJ" and get the address info for the nearest locations.
