I have been messing around on Mobage for a while and have recently run into a snag with a few games such as Idolmaster Cinderella, and another called Phantom babe, these games don't allow you do use extras reward (Non-Coin gachas) or with phantom babe you cant claim any gifts {without an phone number authenticated account (japan only)}. If anyone would be willing to help me out that would be greatly appreciated. I tried searching and using methods such as the internet Phone numbers and the Yahoo.jp account which did not work.
