Receiving device has the needed locale installed?

If you are able to receive other text messages in Persian on the receiving device, then you need to check the modem.

I can help you about that, you need to send message as PDU format.

Tanks.
Please change my code,

my send code is :

myport.BaudRate = 921600;
myport.Parity = Parity.None;
myport.StopBits = StopBits.One;
myport.DataBits = 8;
myport.ReadBufferSize = 10000;
myport.ReadTimeout = 1000;
myport.WriteBufferSize = 10000;
myport.WriteTimeout = 10000;
myport.RtsEnable = true;

if (txtTel.Text.Trim() != "")
{ try
{
if (!myport.IsOpen)
myport.Open();

myport.DiscardOutBuffer();
myport.DiscardInBuffer();

myport.WriteLine("AT+CMGF=1\r");
myport.WriteLine("AT+CMGS=\""+txtTel.Text.Trim()+"\"\r");
myport.WriteLine(txtMessage.Text.Trim() + '\x001a');

Thread.Sleep(500);
if (myport.ReadExisting().Contains("ERROR"))
MessageBox.Show("Device does not support this command or any other problem...");
else {
MessageBox.Show("Sent successfully", "", MessageBoxButtons.OK, MessageBoxIcon.Information);
} myport.DiscardOutBuffer();
} catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
finally
{
myport.Close();
}
}
else
{
MessageBox.Show("Enter Tel"); txtTel.Focus();
}
