Hi, 

I start to work in Luxemburg at the beginning of 2013. Can you recommend a good provider for an UMTS stick, that is Linux friendly?[1] 
I need coverage mostly in Luxemburg city and on the road from Remich to Luxemburg.
If a mobile phone with tethering is the best solution, I am interested in that as well.

[1] An example of a non-Linux friendly company in Germany: stick is prepaid and works fine, but to charge your prepaid account, you need a Windows software.

Thanks
Thomas
