i am going to japan in a month on exchange and i want to have a phone to communicate with my host family, i have a nokia n8 and i am with optus, will my phone work if i am in japan if i get a different sim card? oh and i live in australia.
I'm from Australia, I also have an N8 and I've also travelled overseas with it. You'll need to go to optus, or ring them and activate international roaming.
