{
    static void Main(string[] args)
    {
        MessageRequest r = new MessageRequest();
        r.ApiKey = "YOUR_ACCESS_KEY";
        r.To = "PHONE_NUMBER"; //Must in format E164 (32496XXYYZZ)
        r.Message = "Hello World !";

        MessageApi m = new MessageApi();
        MessageResponse resp = m.SendMessage(r);

        Console.WriteLine(resp.ResultDescription);

        Console.ReadLine();
    }
