That's simple CSD (see other posts of this thread). AFAIK it's supported by 
all carriers in Germany. I used it ~year2000 with a Nokia 6210 and a Palm5 on 
O2 without any problem. You can access internet via provider's accesspoint, 
or you can dial up a modem connected number at your home to run your own 
accesspoint/proxy. Anyways it's normal connection fee (as of y2k).
