سلام عليكم 
I need to send SMS from vb.net program through a GSM modem that is connected to the computer. My code works normally in english language, but when I tried to send Arabic letter I received ???? on the destination device.

my code is as below

 With ser
'.Encoding = System.Text.Encoding.UTF32
            .Write("AT" & vbCrLf)
            Threading.Thread.Sleep(1000)
            .Write("AT+CSCS=HEX" & vbCrLf)
            Threading.Thread.Sleep(1000)
            .Write("AT+CMGF=1" & vbCrLf)
            Threading.Thread.Sleep(1000)
            .Write("AT+CMGS=" & ChrW(34) & phonenum & ChrW(34) & vbCrLf)
            Threading.Thread.Sleep(1000)
            .Write(message & ChrW(26))
        End With


Note:- ser means serialport, message is a string from textbox object

و شكرا جزيلا
