Aussie pre paid one will work with a Balinese/Indo card. My son took his and it wouldn't work as they are locked to the provider for a certain length of time, unless that time has lapsed and you have had it unlocked with Optus it won't be any good.
Make sure what ever phone you take it is unlocked!!!!!!
