Widget for free SMS - callwave

Free SMS services have a number of takers. There are a number of sites which provide this service. For a long time, I was not able to find one which provided good service the world over, and specially in India. Only today I discovered the service by callwave. It's service is better than others, it provides the facility for all over the world and its SMS has a very small reference to the originating site. Moreover, it allows widgets for integration in personalized homepages - google, yahoo, vista etc. This makes it a great, easy to use service. I hope it would stay forever on my google personalized homepage!
