Boke, thank you too, for starting the thread & starting the page!

I've updated the XS4All information slightly.

I will try to add T-Mobile Netherlands and Vodafone Netherlands (mobile & laptop/tethering options), but they have complex AUP, and I don't want to provide incorrect information. Maybe there has to be a disclaimer added, or using 'unverified' and 'verified' tags (or 2 sections). If e.g. 2 credible persons say something is verified, move it over. But who is 'credible'... since its a Wiki, maybe a disclaimer is the lesser of the evil options.

Also,

We need more contributors!

Maybe you can refer to the Wiki in the starting post?
