I realise that there is now a large (and apparently increasing number) of service providers for talk/data SIM cards in Japan, but it seems to me that these can’t be used abroad (according to a friend who uses IIJ and a call to my current Wifi Router provider, the otherwise excellent Asahi Wimax). What I am looking for is a Japanese phone number which I can at least receive phone calls on (I can survive without making them) when I’m out of Japan. To get this, would I have to subscribe to one of the major 3? If so, then I’m going to have to go with Asahi Wimax (I will get a discount with them because I already have the router), and rely on a Skype number when I’m out of the country. It seems that you can’t even leave an automatic message on your number, saying that you’re away and asking people to send you a mail or giving them an alternative way of getting in touch.
Anyone have any other suggestions?
