如何通过使用串口的双SIM卡手机发送短信 [英] how to send sms via a dual sim mobile using serial port

问题描述

我正在使用以下代码向收件人发送短信

I am sending sms to recipients using following code

private void button1_Click(object sender, EventArgs e)
    {
        var com5 = new SerialPort("COM5");
        if (!com5.IsOpen) com5.Open();
        com5.WriteLine("AT" + Environment.NewLine);
        com5.WriteLine("AT+CMGF=1" + Environment.NewLine);
        com5.WriteLine("AT+CMGS=\"" + 03132449297 + "\"" + Environment.NewLine);
        com5.WriteLine("Kashif bhai aap mujhsay kiya kehna chah rahay hen?" + (char)26);            
        com5.Close();                                  

    }

我的问题是:如果我使用单个sim移动usb调制解调器使用上述编码发送短信，则效果很好.但是，当我使用双SIM卡移动USB调制解调器时，无法使用上述编码发送短信.我已经尝试过诺基亚200和三星gt-c3312

my problem is: If i use a single sim mobile usb modem to send sms using above mentioned coding it works fine. but when i use a dual sim mobile usb modem I am not able to send sms using above mentioned coding. I have tried nokia 200 and samsung gt-c3312

推荐答案

您尝试过AT + CSIMSEL = 1吗?

did you try AT+CSIMSEL=1 ?

请参阅本文档中的11.4 AT + CSIMSEL在两个SIM卡之间切换:

see 11.4 AT+CSIMSEL Switch between two SIM card in this document:

http://www. scribd.com/doc/63648056/186/AT-CSIMSEL-在两个SIM卡之间切换

该命令用于选择外部或嵌入式SIM卡.注意

The command is used to select external or embedded SIM card. NOTE

1. 定制支持的嵌入式SIM卡.客户应提供写入USIM芯片组的信息.

1. Embedded SIM card supported by customization. Customer should provide informationwritten into USIM chipset.

如果不存在嵌入式SIM卡(即标准硬件版本)，该命令将被禁用.

The command is disabled if the embedded SIM card isn’t exist, i.e. standard hardwareversion.

定义的值

1 –外部SIM卡

2 –嵌入式SIM卡

2 – embedded SIM card
