Not sure what do you mean by free sms gateway here when you are using your phone.

6630 has a modem. So you can use it. If you can have PC suite (or Ovi suite) in your pc, you should visit these links:

If you do not want PC Suite and want to develop stand alone application, you need to send sms using AT command. You need to use the SerialPort class for this.

In order to use your phone as a GSM Modem connect to it as if you are connecting to a Serial Port. (There are drivers which adapt USB to Serial Port. Your phone drivers might do this).

Once you manage to connect to it you can send commands such as AT+CNMI (to receive) and AT+CMGS (to send).

You might want to connect via hyperterminal to try it out first before you program it.

A good tutorial is here.
