Band should be compatible, so if anything it would be up to SoftBank's policy regarding non-Japanese phones.
Hi all - I would like to know if I would be able to bring my unlocked at&t captivate (us version of samsung galaxy s 1) that is quad band umts/hsdpa (850,900,1900,2100) over to japan and have it work (data, calls, sms - everything) on Softbank (which I already have an account and non-smartphone)? As I understand it, Japan uses WCDMA 2100 for 3G/data, and from what I've read, UMTS = WCDMA, so I would think it *should* work.... right?
any help would be greatly appreciated!
(apologies if this is not the right place to post this question!)
Yes it will work. You'll need to configure your APNs properly and to get S!Mail you'll need to configure an SMS/MMS application to use the right user agent (there's some howto for that in the Japanese Android Phones forum right here).
Yeah, it should be compatible, but I'm not sure how the network will take to you using a non-smartphone sim with a smartphone. If I understand it correctly, there's a different sim for smartphones/iPhones/'dumb'phones, but I'm not sure if it'll detect your Captivate as a smartphone or a dumbphone.
