Data usage

Hello
Im a trully fan of this anime and after tried the game i can say only " awesome" , really no need other words just thanks , but it have a big problem, the enourmous 3G data usage. Of course when im home Wi-Fi solve everything, but if im outside and want to do some co-op or story mode its impossibile due to the limited data plan .
Please solve/fix this problem
