Hi I'm leaving for Japan on the 25th of December, and I really need an phone simcard. I need to make some calls (Skype ToGo) and I need Internet to survive! (20 days!) Does any of you guys know a good prepaid service? Here in the US, T-MOBILE has a reasonable option. If I'm not wrong, about 3 dollars /day for unlimited 2G, Calls and SMSs. I'm looking for something similar. Thank you.
