I have a Nokia 6110 Navigator (now many people know why I decided to buy a N800 and not the N810) I have Orange Data Flat (2.5 GB for 59 CHF per month) price plan. It was very easy to get it working, just walking through the wizard. The provider was supported. What else? The 6110 supports HSDPA and so fast internet is available on the road and that I'm soon switching over to Swisscom and I'm curious if I should take the 5 GB Plan for 69 CHF or 1.5 GB for 49 CHF or if 100 MB is enough (for 18 CHF) each per month...
