I have just received mine.
Some remarks:
-It is indeed shipped by DHL (tracable) for free
-I couldn't register my card using abroadband's internet. The first two steps were OK, but I couldn't load the PayPal page so I copied the URL and registered on my own internet network.
-I am getting the same speeds as on my own Dutch Simyo sim card on the KPN network.
-You can check your usage online on the abroadband site. It is updated instantly.
-The way in which it connects to a network is very strange. According to their website they should support KPN and Vodafone in The Netherlands. When in 'automatic' mode it connects me to Vodafone NL. When I manually search for networks and select KPN, KPN denies my sim card and at the same moment I also loose my connection with Vodafone. After that I also cannot connect to Vodafone any more (it also denies my sim card)

The only way I could get it to connect to KPN is by forcing WCDMA, restarting, and then letting the phone select the network automatically.
This all seems very strange to me, as I haven't experienced it with any other sim card. Does somebody know a possible cause of this?
