not received them yet. i got one from HK (x-sim) one from Taiwan (inex hypersim).
not sure if they are going to work well here or not
i will let you know later
not likely
it does not support 3G 2100MHz, that's the European 3G standard band width
it only can be used in Japan 3G 1700MHz. they have their own band width
maybe someone can try in Europe ?~
