Anybody here have an idea how to read SMS in SIM using VB.NET? I'm using a Broadband Modem. I can already send SMS, but I can't find out how to read SMS from the SIM and display in a `datagridview`. 

Here is my code to send SMS:

```
SerialPort1.Write("AT" & vbCrLf)
SerialPort1.Write("AT+CMGF=1" & vbCrLf)
SerialPort1.Write("AT+CMGS=" & Chr(34) & num & Chr(34) & vbCrLf)
SerialPort1.Write(message & Chr(26))

```

How about reading SMS?

Many thanks in Advance.
