In the middle of December, you will be able in Japan to purchase Wii Points directly from your mobile phone, without needing any credit card. Simply put, from your mobile phone you will have the possibility to add Wii points to your account (1000, 2000 or 3000 Yen), without the need of using a credit card; the amount you choose will be later on added to your mobile phone monthly bill. Simple and painless !
