I am here in ireland using 3 mobile broadband. Sometimes if i go travelling i will take the sim from dongle and put it into n900 to access the internet. You can start using the net by choosing 3 network broadband from available options via the internet connection widget. You can also send and receive text as well as receive calls but not make calls. Plus, i was in belfast on holiday a few months back. I used the same method to get to the internet. The is no roaming charges.
