Send Free Sms To India Via Email

To send sms freely, you have know the operator and the area of the service. Then, open your webmail like Gmail, Yahoo, or Rediff and send email to the MobileNo@OperatorWebsite.com and the mobile user receives it as a normal SMS, but "from" will show your email address rather than mobile number. I use Aritel AP and the messages are delivered instantly like the normal SMS. If you have to send message to an Airtel Mobile in AP just send email to MobileNo@airtelap.com.

Note: When I checked for the DNS records of airtelmail.com, I have seen that it has been owned by a company in Florida, USA and not by Bharthi, so I am in doubt and don't think it works. Rest are okay. Check it and post your comments.
