Because my sister is a Stewardess and everywhere where WLAN is available, she can log into the Internet over her I-Phone, even without a Sim Card.
For example, at every Starbucks coffee shop, or Hotels, Bars and so on who offer free WLAN.
Now my question, does the same apply to Japan?? Is it possible to use your I-Phone from home, to browse the web in Japan?
Thanks in advance guys
