does hitachi w32h cellphone can read other country's sim card? like SMART sim? my older brother has one hitachi w32h phone came from japan, unused and i think it's suited for me and it is my crush cellphone model :D i like it's features especially the messaging, it's fun to text with my friends with that, if possible. but when i try to turn it on, it said UIM card error. and where can i buy it's SD mini card? i can't find it in some stores is it possible also to unlock it in our country? [philippines] thanks
