Hi Muniraj,

Those commands are Sagem specific, so I don't have any experience using them.

Maybe someone else will come along with some ideas for you.

I was curious, so I did download their API specification for a quick look.

It might just be a typo in your message here, but the value you are passing to AT+KPSSEND does not match the message id returned from AT+KPSW.

Beyond that, I don't have any suggestions, as that's the first time I've ever seen that Sagem specific API.

Actually ... I do have one other suggestion.

Get rid of the the leading 0's in your IP addresses. E.g., instead of 100.001.201.171, use 100.1.201.171. I have experienced APIs in the past that get very confused by leading 0's in an IP address, and interpret the address incorrectly.
