This is really good website to send Free SMS to any mobile (CDMA or GSM) anywhere in India! Pretty quick service..
Just one thing to notice, they allow you to use appx. 92 characters for your message and append an advertisement in rest of the message! Service is pretty quick (in 15-20 seconds, other party will receive it!)..
