O2 XDA II With Roaming Globe Simm

[DGA650815]

Appreciate an advise from anyone on my current disappointment. Please help. I bring my O2 with me here in Japan with a roaming globe simm card from Manila. Card is working properly. My prostration is that I can't use my O2 phone here in Japan which maybe because of the communication setting that they are using. Somebody told me that there are few CP comming from other countries worked here and most of those are designed with 3G.

Is there anything I should do to make this O2 work?

Thanks...
