hi there
first thing you need for learning j2ME is
you should have enough time and patience.All of us are programmers for whom 24 hrs.were not sufficient,still we
did not give up.
You can send & receive sms in your application.
mobileno = "09886312140" ;
yourmessage ="hai - how are you ? " ;
senderAddress = "sms://:" + mobileno ;
clientConn = (MessageConnection) Connector.open(senderAddress);
clientConn.send(yourmessage);
Regards
Gopinath
