The server tells me there was an error sending the message, what causes this?

This is most commonly caused by using an incorrect username or password or a temporary network problem.

Make sure that your username and password are correct (if you have forgotten them, click here). Also ensure that you're network connection is set up properly and you can contact http://winsmsserver.cardboardfish.com on port 80.

You can test this by opening a command window and making a telnet connection to http://winsmsserver.cardboardfish.com on port 80.

If this fails you should contact the support for your network and make sure that any firewall present is allowing access to http://winsmsserver.cardboardfish.com on port 80.
