Damn -- this is amazing / hilarious / absurd. Apparently the manufacturer followed up with a product called WorldPort GBX:
By 2001 Datel had invented a new version of the SmartCom called World Port GBX which actually had a small modem built-in.
Now the catch with the Worldport GBX was that it would only work from telephone lines in the United Kingdom, so I'm guessing it's safe to say that neither the Worldport GBX or the SmartCom was a great success back then...
