Well, in hindsight next time I will order from sim4travel.com. I only had a chance the first day in Amsterdam to buy a sim, and the Vodaphone clerk apparently misunderstood. I wanted at least a week's use with international calling, and wound up with one day's use and only local. Then I could not get Gizmo or Google Talk to work although they had been fine at home. Not much fun being so far from home and unable to call anyone...
