data connection by my hand, so i go to Control Panel\Network and Internet\Network
Connections , right click the connection and click 'connect', i always get the error
'678, remote no response .....'. I do not why this connection can not connect

Hi,
Can you confirm if you do this?
private void frmSMS_FormClosing(object sender, FormClosingEventArgs e)
{
if (mobileGateway != null)
{
mobileGateway.Disconnect();
mobileGateway.Dispose();
mobileGateway = null;
}
}Thanks
