Thanks! Its working.

But i encountered next problem - SmppClient.SubmitText send field registered_delivery always set to 0. This method doesn't usable with lazy quering of messages delivery, isn't it?

This code
try
{
QuerySmResp resp = client.Query(id, SRC_TON, SRC_NPI, SRC_ADDR);
}
catch (Exception e)
{
AddToLog(e.Message);
AddToLog(e.StackTrace);
}
called with small timeout after SubmitText (when QUERY_SM_RESP cotains null in field final_date ), generates that exception
Unhandled ...
