Hi Pratik,

It's difficult for me to answer, because I don't know how far you've gotten, and I know nothing about your system configuration.

So I mostly can only respond with questions ...

Does NowSMS receive your message? In the configuration program, the "SMS Received" counter is increased every time a message is received. Are you getting that far? If not, what is NowSMS using to receive messages? A GSM modem? What model? (Also see

If NowSMS is showing messages being received, then how is your 2-way command defined? Is the SMS command prefix set to * ... to get started, that would be a good idea, it means to route all received SMS to your command.

If you've done that, and confirmed that NowSMS is actually receiving the message, then my next suggestion would be to enable the SMSDEBUG.LOG. (Checkbox option on the "Serial #" page.) A lot of the info you will see in SMSDEBUG.LOG will not be helpful, but it will show any HTTP 2-way command URL that is generated, and what HTTP response is returned by your servlet. Often that can show surprises where the URL is not quite what was expected.
