I heard about B-mobile's AEON SIM cards the other day. You can get up to 100kbps unlimited* for 980 yen per month, or 400kbps unlimited* for 2980 yen per month. *Looks like some people found out there is a limit of 3million packets for 3 day period. The plans specifically exclude Skype and other VOIP applications. This is only sold at AEON locations.

Will a temporary visitor be able to sign up for these plans?
