Hi all,
   I make a software for sending SMS using for GSM Modem. It's works fine. But my  problem is now that it couldn't send more than 160 character.   
 The error is given below:
 " Text is two long. A maximum of 160 resulting septets is allowed. The current input result in 288 septets(given by me)."  
 My code is given below when I click on my Send button:
"
//
 port connected successfully SmsSubmitPdu pdu = new SmsSubmitPdu(message, cell, ""); 
comm.SendMessage(pdu);   
"
 Please help me to find the solution with C# code. Because I have tried it for last two days. But got no solution.   
 Thanks in advance.
