Using 3G iphone in japan
 

Hi.. i'm from singapore and will be travelling to japan next month and i'm wondering if the 3G iphone can be use in japan. Can someone hlep me on the above subject.. Thanks alot

it should work in Japan.. but for confirmation, you should visit Softbank's shop near the place you'll be staying..

It should work. I was recently in Japan, and my friend has a 3g Iphone and she used it to call home, and an international phone someone had in Japan.

thanks alot !!:)

You have to call AT&T and get it activated to use in Japan.
I did that with mine.

Can I do the opposite? Use At&t for the next two weeks with my softbank iPhone?

Hi..yeah it does.
I've used mine before.
I'll usually use Softbank..more stable network.

It really a geographical situation as well, I know that here in Yokosuka the reception is really not that great but if you are going to a more flat area like Tokyo for example you should be fine. My friend only uses it for browsing XD so like the others have said you should call AT&T.
