A1522 in Japan

I am looking for some knowledge / advice on bringing an iPhone to Japan. I know I could just buy one there but rather bring my own. I currently own : USA A1522 (T-Mobile) Factory Unlocked iPhone 6 Plus. The question is, will this do? I plan to reside in Japan for at least 2 years so I need a dependable phone for everyday use. I know there's different bands or whatever, I really have no clue what the difference is so that's why I need your help! :) I don't know if I'm better off trading this for a A1524, or something else? I want to be able to have talk, text, and data through a service (maybe prepaid like b-mobile to have a cheaper bill?). Thank youuuu

Yes, it will work.

^ so why do people recommend the unlocked sprint iphones?

...so you can escape Sprint's crappy service and actually get a signal somewhere ;)

Being serious now, where are you seeing Sprint phones specifically being recommended? All unlocked current model iphones should work essentially the same on a Japanese sim.

Haha! I'm not sure where exactly I read it, because I wasted a couple hours researching everywhere. Few different people commenting that the A1524 unlocked is a must. People complaining that the "US AT&T" iPhone isn't working in Japan. I read somewhere else that the extra bands in the Sprint iPhone is needed to use in Japan. I have a headache from all this reading and can't find a firm answer.

not a firm answer there, either. o.O

The post from Dec 18, 2014 seems to be a pretty definitive confirmation that an unlocked t-mobile iphone will work.

I read somewhere else that the extra bands in the Sprint iPhone is needed to use in Japan.

If you mean the CDMA band, it's virtually useless as the only CDMA provider in Japan doesn't sell non-contract service.

Thank you. You've been awesome.

You can check here for some details.

Yes, but note that the official compatibility list is notoriously misleading as it only lists officially supported carries that sell contract service. To actually check compatibility you have to look at the supported LTE bands, in which case you'll see that virtually all unlocked iphone 6 models should work on the local Japanese carriers.
