smslib not sending sms why?

Question

I am trying to send a sms with smslib but It did not send the message, can somebody guide me on this?

this is my code:

import org.smslib.AGateway;
import org.smslib.IOutboundMessageNotification;
import org.smslib.Library;
import org.smslib.OutboundMessage;
import org.smslib.Service;
import org.smslib.modem.SerialModemGateway;

public class SendMessage
{
    public void doIt() throws Exception
    {
        OutboundNotification outboundNotification = new OutboundNotification();
        System.out.println("Example: Send message from a serial gsm modem.");
        System.out.println(Library.getLibraryDescription());
        System.out.println("Version: " + Library.getLibraryVersion());
        SerialModemGateway gateway = new SerialModemGateway("modem.com1", "COM4", 115200, "Huawei", "");
        gateway.setInbound(true);
        gateway.setOutbound(true);
        gateway.setSimPin("0000");
        // Explicit SMSC address set is required for some modems.
        // Below is for VODAFONE GREECE - be sure to set your own!
        gateway.setSmscNumber("[phone]");
        Service.getInstance().setOutboundMessageNotification(outboundNotification);
        Service.getInstance().addGateway(gateway);
        Service.getInstance().startService();
        System.out.println();
        System.out.println("Modem Information:");
        System.out.println("  Manufacturer: " + gateway.getManufacturer());
        System.out.println("  Model: " + gateway.getModel());
        System.out.println("  Serial No: " + gateway.getSerialNo());
        System.out.println("  SIM IMSI: " + gateway.getImsi());
        System.out.println("  Signal Level: " + gateway.getSignalLevel() + " dBm");
        System.out.println("  Battery Level: " + gateway.getBatteryLevel() + "%");
        System.out.println();
        // Send a message synchronously.
        OutboundMessage msg = new OutboundMessage("[phone]", "que onda como andas!");
        Service.getInstance().sendMessage(msg);
        System.out.println(msg);
        // Or, send out a WAP SI message.
        //OutboundWapSIMessage wapMsg = new OutboundWapSIMessage("306974000000",  new URL("http://www.smslib.org/"), "Visit SMSLib now!");
        //Service.getInstance().sendMessage(wapMsg);
        //System.out.println(wapMsg);
        // You can also queue some asynchronous messages to see how the callbacks
        // are called...
        //msg = new OutboundMessage("309999999999", "Wrong number!");
        //srv.queueMessage(msg, gateway.getGatewayId());
        //msg = new OutboundMessage("308888888888", "Wrong number!");
        //srv.queueMessage(msg, gateway.getGatewayId());
        System.out.println("Now Sleeping - Hit <enter> to terminate.");
        System.in.read();
        Service.getInstance().stopService();
    }

    public class OutboundNotification implements IOutboundMessageNotification
    {
        public void process(AGateway gateway, OutboundMessage msg)
        {
            System.out.println("Outbound handler called from Gateway: " + gateway.getGatewayId());
            System.out.println(msg);
        }
    }

    public static void main(String args[])
    {
        SendMessage app = new SendMessage();
        try
        {
            app.doIt();
        }
        catch (Exception e)
        {
            e.printStackTrace();
        }
    }
}

and my result:

Answer 1

This example has extra line of code about SMSC-number. I have played with this same library and in my code there is not any SMSC - at any line of my code.

It is a suggestion, "if needed", and I certainly believe getting rid of it solves your problem. You most probably don't know what you exactly have to put on it, so better leaving it out. Then modem will not try to do this routing manually to given number but it can make it to the correct, what it knows by SIM settings on the SIM card.

Another thing I would check is that the modem really answers from COM4 port. Although now it seems to do so, because the signal strength is read. But check this always, because every startup of server can map the device to different port. I was at least having this kind of problem on Linux side.
