A couple of years ago, I wrote a blog post on the quickest and easiest way I knew of to get your international iPhone working in Japan. And, after one of my friends traveled to Japan late last year, I can confirm that renting a Japanese SIM card from JCRCorp is STILL a quick and viable option, with unlimited voice, and unlimited data.
That being said however, while JCRCorp is really good, their rates start to get quite expensive the longer you stay in Japan. It’s probably fair to say that this is a service that is geared mainly towards tourists of Japan; those only staying for a short while before promptly leaving.
So last year, when I went to go work at pixiv, something I knew that I would be doing in upwards of 7 months, I figured I’d have to do something else. I also figured that since I would be going to Japan on a working visa, I could most likely pop into a telco shop and just grab a pre-paid SIM card.
So, armed with my carrier-unlocked iPhone 5 (Bought outright from Apple), I traveled over to Japan!
Unfortunately, when I got there, a few of my friends who had traveled over there a few months early, broke the news to me; apparently a ‘pre-paid SIM’ as we know and understand it in Australia, doesn’t really work in Japan.
