installing datacard

can any 1 pls tell how to use vodafone datacard on suse 11.1?

Is it a GPRS/3G card?
Insert it and see if it pops up in the knetworkmanager.

it pops as a mass device on dolphin

yes its the same card

This card is a mobile modem + a virtual CDROM. What is happening in your case is that is is being recognized as a CDROM when inserted and that is why is coming up in Dolphin. If you eject that drive, it comes to modem mode. It should then appear in knetworkmanager as a mobile modem (a mobile icon will come up there).

However, even after that, there were problems reported. So, update your system first and try.
