i am subscribed to AU, i've had my phone for about 6months.. i reccommend it, i know many of my friends have other carriers, but AU has the best reception. I have the Sony Ericsson A1301S. But if your overseas the best one would be the global passport.. so that you can receive and make calls, otherwise there is no use in buying a japanese keitai..

hmmm.. i mean in indonesia there telkom flexi it use SCMA 2000 1x so i want AU keitai so i can using it with Flexi that why i wanted it,
did all AU phone have bilingual service?
