dell wireless broadband card5530: configuration issues

Except for a couple of small things i've gotten along quite well with my Lattitude 6400...
only problem is: my WWAN broadband card (dell wireless 5530) doesn't quite work as I want it to - or rather the configuration tool doesn't do what I want it to.
my regular sim-card i can use without any problems - but since I spend quite a bit of time in Austria and need an internet connection there I got a prepaid wireless internet account. To correctly configure it I need to

-configure the ip by dhcp but at the same time
-set the dns servers manually

anybody know how to do this? I only can set everything to dhcp or configure the ip adress manaully as well - and that isn't possible

 

Create a couple of netsh.exe batch files for your different SIMs?
