Send messages with whatsapi.net?

Question

I want to send messages using whatsapi and this was my try

string nickname = "Test";
string sender = "xxxxxxxxxxxxxx";         
//My Phone Number tryed with 049xxxxxxxxxxxx, 0049xxxxxxxxxxxxxx, 49xxxxxxxxxxxxxxx, xxxxxxxxxxxxxx
string imei = "xxxxxxxxxxxxxxxxxxxxxxxxx";//My IMEI 
WhatsApp me = new WhatsApp(sender,imei ,nickname,true);
me.Connect();
Console.WriteLine(me.ConnectionStatus);// I get a Connection!
Console.ReadLine();
me.SendMessage("xxxxxxxxxx", "This is a Test!");// Send Message
//No Message received :(
me.Disconnect();
Console.WriteLine(me.ConnectionStatus);
Console.ReadLine();

Now where is my mistake? and how I'm doing it right?

I'm using this version: https://github.com/perezdidac/WhatsAPINet.

First I just want to send messages. When I try to get a request from the WART, I just get this message:

Could not request code using either sms or voice.
SMS: {"status":"fail","reason":"no routes","retry_after": 3600}
Voice: {"status":"fail","reason":"no routes","retry_after": 3600}

    WhatsApp wa = new WhatsApp("your number", "your password", "pankaj", false, false);
    wa.OnConnectSuccess += () =>
    {
        Response.Write("connect");
        wa.OnLoginSuccess += (phno,data) =>
        {
            wa.SendMessage("to", "msg");
        };

        wa.OnLoginFailed += (data) =>
        {
            Response.Write("login failed"+data);
        };
        wa.Login();
    };
    wa.OnConnectFailed+= (ex)=>
    {
        Response.Write("connection failed");
    }
