See the SMSCs list here http://kannel.org/compatibility.shtml. I remember using a Wavecom GSM Modem that connects via the serial port. The modem I had was not supported by Kannel, but I was able to tweak the existing driver to make it work with the newer model. Having the source code is so much more fun, ain't it? IIRC, Kannel gateway is capable of posting the contents of the SMS recieved to any specified URL. I used a simple PHP script to recieve the SMS and then do whatever I wanted to do. You can also send out SMSs(e.g confirmations) by posting to an URL that Kannel Gateway makes available. But GSM Modems may be difficult to locate in India. I got mine from Singapore. Kannel is much more powerful - if you are only using the SMSC, it is probably overkill. Of course, you need a SIM card for the GSM Modem to work.
