You can use your Japan KDDI AU locked iPhone 6 Plus in the U.S. with an AT

I'm visiting the U.S. for 5 weeks and have a normal, KDDI AU iPhone 6 Plus. When I arrived in the U.S. I noticed the carrier signal said AT&T. So out of curiosity I went to an AT&T shop this morning and they said as long as it shows AT&T you can use it with a GoPhone prepaid contract.

So they took out my AU SIM and put in an AT&T SIM and sure enough it works as is! No unlocking necessary!

I got the $45/month unlimited talk and text + 1.5 GB plan.

I'm happy that I could use my Japan iPhone in the U.S. so easily and so just wanted to let others know who might be in a similar situation.

When I turned my phone on, by the way, I also got a text message from AU welcoming me to the U.S. and telling me that for a flat rate of ¥2,980/day (expensive!) I could use my iPhone 6 Plus as is. Checking online, it appears you need to turn on roaming for that, which I did not do.

It seems much better to just get an AT&T domestic card for your trip.

Anybody else with similar experiences?

Hey Doug,

First of all thx for shared the info about using KDDI AU iPhone in USA. its really helped, appreciate it

I noticed that u also added more details about unlock KDDI AU iPhone 7 Plus

> With the iPhone 7 Plus you can automatically get them unlocked for free by the carrier in Japan because of law changes a couple of years ago.

I brought iPhone 7 from KDDI AU and it has more than 6 months and i got a plan to travel European country next month and I'd like to use local SIM so here's the question how do i unlock my KDDI AU iPhone?

I was told I can submit unlock request via web, but i didn't find a link to submit it. can u plz help me with that?

Sorry - but I don't have any additional info other than that posted on that web site. I myself switched to Softbank last year. I suggest calling AU customer support. I believe there is an option to talk in English.

Sorry I can't be of more help. 😟

Does anybody happen to know if this is also true for the iPhone 7 Plus from KDDI AU?

With the iPhone 7 Plus you can automatically get them unlocked for free by the carrier in Japan because of law changes a couple of years ago. But I was thinking of taking a trip to the U.S. in April, just under 6 months, and was wondering if it works like it does with my iPhone 6 Plus - works on AT&T without unlocking.

Thanks.
