(keitai-l) Nokia 6650

Hi,

Has anyone tried a Nokia 6650 in Tokyo?
Is there a large WCDMA network, or is it just available in some places?

Suppose I use a dutch Vodafone sim card, will this work?
Will the network support roaming?

It would be interesting to have a phone that works both in Japan and in
Europe.

Thanks,
Stephan
