Are you sure about this, Sumit ?
Reason is I see STK commands like SET_MENU, etc, these STK commands are
probably low level commands to the Manufacturer's Equipment (handset) and in
turn have to be triggered using the Java card APIs. I saw some 20-25 STK
commands but again, I was not sure if there was a STK command for retrieving
SMSes from SIM.
I do not want to install anything on the handset and therefore do not want
to use J2ME in this case.

Regards
Kallol
