推荐答案
是的，有一个解决方案。
您需要和服务器（计算机）上的GSM调制解调器一起使用SIM卡（可以为任何公司的免费短信计划支付租金[sprint，at& t ...]）。有了你的手机上的计划，你可以免费无限制短信，只需支付租金，比支付每条短信更好。
GSM MODEMS：
USB（我用这样的一个测试）
3G WCDMA GSM WIFI 7.2 Mbps HSDPA USB Dongle
中兴MF190 3 G GSM 7.2 Mbps USB移动宽带调制解调器
另有多张SIMS卡：
MódemsUSBGSM 8 Puertos批量短信
另一种调制解调器：
M2MmódemM2MRS232MódemQ24plus
APP（c＃）：
SMSapplication.zip
首先连接到COM端口，应用程序显示连接状态，在第二个选项卡发送短信中输入手机号码和信息，然后按发送。
代码（按钮）：
Yes there is a solution.
You need and GSM modem on you server(computer) with a SIM card (could pay a rent for a plan with free sms in any company [sprint, at&t...]). With the plan like on your cellphone you have free unlimited SMS, only pay a rent, better than pay for every single SMS.
GSM MODEMS:
USB (I made test with one like this)
3G WCDMA GSM WIFI 7.2 Mbps HSDPA USB Dongle
ZTE MF190 3 G GSM 7.2 Mbps USB Mobile Broadband Modem
Another with multiple SIMS cards:
Módems USB GSM 8 Puertos bulk sms
And another kind of modem:
M2M módem M2M RS232 Módem Q24plus
The APP (c#):
SMSapplication.zip
First connect to the COM port, the application show the status of the connection, in the second tab "Send SMS" put the cellphone number and the message, then press send.
The code(Button):
private void btnSendSMS_Click(object sender, EventArgs e)
{
//.............................................. Send SMS ....................................................
try
{
if (objclsSMS.sendMsg(this.port, this.txtSIM.Text, this.txtMessage.Text))
{
//MessageBox.Show("Message has sent successfully");
this.statusBar1.Text = "Message has sent successfully";
}
else
{
//MessageBox.Show("Failed to send message");
this.statusBar1.Text = "Failed to send message";
}
}
catch (Exception ex)
{
ErrorLog(ex.Message);
}
}
寄送课程：
Send Class:
public bool sendMsg(SerialPort port, string PhoneNo, string Message)
{
bool isSend = false;
try
{
string recievedData = ExecCommand(port,"AT", 300, "No phone connected");
recievedData = ExecCommand(port,"AT+CMGF=1", 300, "Failed to set message format.");
String command = "AT+CMGS=\"" + PhoneNo + "\"";
recievedData = ExecCommand(port,command, 300, "Failed to accept phoneNo");
command = Message + char.ConvertFromUtf32(26) + "\r";
recievedData = ExecCommand(port,command, 3000, "Failed to send message"); //3 seconds
if (recievedData.EndsWith("\r\nOK\r\n"))
{
isSend = true;
}
else if (recievedData.Contains("ERROR"))
{
isSend = false;
}
return isSend;
}
catch (Exception ex)
{
throw ex;
}
}
我没做这个应用程序，我在互联网上找到...我做了测试，它的工作。
要用gsm调制解调器构建你的网络，你必须要考虑：
- 连接调制解调器的物理服务器（可能是你的电脑）
- 支付短信（SIM卡）的租金计划
- 支付静电IP，或noIP，din DNS，无论如何，让你的服务器在线
GSM调制解调器重新接收AT命令，这就是c＃应用程序所做的，发送AT命令到调制解调器。

我希望它有所帮助
I didn't make this app, I found on internet... I made test and It's worked.
To build your web with a gsm modem you have to considerate:
- Have a physical server with the modem connected (could be your computer)
- Pay a rent plan for SMS (Sim cards)
- Pay a static IP, or noIP, din DNS, whatever, to put you server online
The GSM modem recive AT Commands, thats what the c# application does, send the AT commands to the modem.
