After extensive research I've decided to purchase a mobile Wifi from Japan Wireless for my husband while we're in Japan next week. This is primarily to access the internet, skype and receive e-mails from work in Australia.
The questions I have is
a. will his iphone 4 be compatible with Japan?
b. do I need to purchase a prepaid SIM data card?
There seems to be so much hype about the difficulty of this process it's seeming too easy. Would value any advice before I push the "buy now" button! :)
