Seems in my travels around the boards that there was talk about the procedures for UK.

Are you with Vodafone?

I'd give your carrier a call and ask about the settings for UK Pearl modem use. I am not too sure, but if you are using XP the concepts are the same regardless of where you reside.

I do note that in Europe they do NOT have the same unlimited data plan as that U.S. T-Mo customers enjoy. Don't they bill you by usage over there?
