这是我的代码:

根据这个页面,该CreateConcatTextMessage方法返回一个类型的数组,SmsSubmitPdu[]但是,当我尝试发送它时,SendMessages我得到一个MessageServiceError 500.我错过了什么？

       SmsSubmitPdu[] pdu2;

        try{
            pdu2 = SmartMessageFactory.CreateConcatTextMessage("My name is Barry Allen. And I am the fastest man alive. When I was a child I saw my mother killed by something impossible. My father went to prison for her murder.", "+639234597676");
            comm.SendMessages(pdu2);
        }

        catch (MessageServiceErrorException e500){
            MessageBox.Show(e500.ToString(), "Information", MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
        }
        catch (CommException e501){
            MessageBox.Show(e501.ToString(), "Information", MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
        }
