Most operators (at least in India) have disabled their email to SMS gateways - for the simple reason that they do not earn any money on SMS sent via this route. I would suggest that you verify that the Airtel gateway that you are connecting is indeed operational, and available to outsiders.
There are several paid SMS gateways available in India. You could Google for them. I have successfully used those for sending SMS to mobile from Java code.
