I try to send a sms with tcp socket with the java code but I still have a return err: 609.
here is the message I send:

/%20sendmsg?user=admin&passwd=mdp&cat=1&enc=1&priority=3&modem=0&to=%22xxxxxxxx%22&text=Hellow.

with xxxxxxxx is msisdn number.

while ((line = br.readLine()) != null) {
System.out.println( “Received line iSMS :”+ line);
