What's the correct model to get for use in Japan (and how!)?

Still love my Z3 but MM OTA update fried the wifi&bt within a week. (Bad Sony. Bad.) So OP3 I'm ready for you.

I'm going to order a USA version and have my friend ship it to tokyo.

• question1- Is there a better way to get one? After all, it's originating in China...


• question2- Is USA version the way to go? The only info I have to rely on is the result from http://willmyphonework.net :

OnePlus 3 North America Model + Japan + Japan Travel SIM (data only) 2G Network: Carrier Network does not support 2G 3G Network: 2100MHz 4G LTE Network: Band1-2100MHz

my Z3 D6653 works fine here in tokyo and is described as:

Quote:

FD-LTE Bands 1, 3, 5, 7, 8, 28, 40, 41, 42, 43, TD-LTE Band 40; UMTS HSPA+ 850 (Band V), 900 (Band VIII), 1900 (Band II), 2100 (Band I) MHz; GSM GPRS/EDGE 850, 900, 1800, 1900 MHz

Help getting XT1575 working again while in Japan. Please!

I'm in Japan for a couple of weeks for work and signed up for the Japan pack that Sprint offers. I spent almost an entire week working with Sprint support ( :eek: ) trying to get data roaming working properly on the phone without much luck (voice and text worked great), but yesterday I lost all connectivity but wifi. Figuring I must have changed something I shouldn't have, I saved everything I could and did a hard reset on the phone.

It still won't connect to any networks. I've re-downloaded PRL and device configs over wifi in the settings but it doesn't even attempt to connect to any wireless networks, or see any for that matter.

I have 2 guesses here but I'd like some kind of confirmation here before I take any action.

1: Maybe my radio firmware is corrupted somehow? I'm not exactly sure how to check it but it just doesn't seem to be doing much of anything. In the SIM status page it says searching for network, but I have no way to know if that's really the case.

2: Since the phone has a Sprint SIM, does it has to be on an actual Sprint network to initialize the networks? (Not Softbank's network here in Japan?) I spent over an hour on Google Voice with them last night trying to get an answer/help but got absolutely nowhere.

The phone is currently all stock but I have no problem unlocking and installing recoveries/software/roms if need be. Any ideas what I can do here or am I just stuck without communication until I get home next week?
