Send SMS with SmppClient class

public static async Task SendHelloWorld()
{
    LogManager.SetLoggerFactory(new ConsoleLogFactory(LogLevel.Verbose));

    using (SmppClient client = new SmppClient())
    {
        try
        {
            if (await client.ConnectAsync(new DnsEndPoint("smpp.server", 7777, AddressFamily.InterNetwork)))
            {
                BindResp bindResp = await client.BindAsync("username", "password");

                if (bindResp.Header.Status == CommandStatus.ESME_ROK)
                {
                    var submitResp = await client.SubmitAsync(
                        SMS.ForSubmit()
                            .From("short code")
