It looks like there are some users on here who are currently living in Japan so I thought someone on here might be able to help me. I lived in Japan for a year about 4 years ago, and I will be returning for a month-long trip this April. When I previously lived in Japan, I was told that the only way to get a cell phone was if you had a gaijin card. I was not aware of any pay-as-you go plans at the time. I'd like to be able to use my unlocked iPhone on my trip with a Japanese pay-as-you go sim card instead of getting raped by ATT's international plan. Is this possible in Japan today? What is my best option for using my iPhone on a month long trip to Tokyo?
