Thanks Cookiedough for the information, I thought china phone might be supported all frequencies for Mt6582 chipset, since they export to different country and multi language support and just needs to change modem driver, maybe I'm wrong, so maybe the best way to change modem driver manually if visit to japan or Korea or other countries....
