GSM COMM cant send more than 160 characters sms

I have searched a lot but still couldnt find exactly what am looking for.

Actually i'm working on a winforms app that will allow user to send bulk sms. What i have acheived so far is that i can send messages that are <= 160 characters but problem occurs when a message gets longer that 160 characters. I don't get any error and sms seemed to have been sent but its not actually.

I'm sharing my code snippet that is used to send sms. Please have a look at it and letme know where the problem is.

Thanks.

SmsSubmitPdu[] pdus;

int len = message.Length;

if (len <= 160)

{

comm.Open();

pdus = SmartMessageFactory.CreateConcatTextMessage(message, number);

foreach (SmsSubmitPdu pdu in pdus)

{

comm.SendMessage(pdu);

}

comm.Close();

}

else

{

comm.Open();

pdus = SmartMessageFactory.CreateConcatTextMessage(message, number);

foreach (SmsSubmitPdu pdu in pdus)

{

comm.SendMessage(pdu);

}

comm.Close();

}
