Thread: Japanese iPhone work abroad?

  1. #1
    Default Japanese iPhone work abroad?
    Will a Japanese iPhone that is unlocked work in other countries with a GSM SIM? Also will a factory unlocked Hong Kong iPhone work in Japan with a Japanese prepaid SIM? I remember that I had to rent a phone when visiting Japan several years back and I was told that Japan has their own proprietary 3G network, but I'm not sure if that still applies today.

    My Softbank 3GS 3.1.2 JB UL has worked fine in the US, Thailand, Singapore, Vietnam, and of course Japan. Have used both 3G and Edge networks as were available. No issues at all.

    Regarding your second question, I have no direct experience, but anecdotal information seems to suggest that this is possible, as does the availability of unlocked HK phones being sold on Yahoo, etc. I have heard, however, that DoCoMo does check EIMEI #, but that at present Softbank does not. If they (Softbank) were to begin EIMEI # checking, they could make trouble for you, like charging you for data, lol.
