I always use Mentari which give me cheap calls to Aus. and fairly good reliability of connection and reception. Can sometimes take a couple of tries to connect but I think that's probably just the way it is in Indonesia. I tried Simpati a couple of years ago and the cheap prefix to call Aus rarely worked at least at that time. It might be fine now.
As Glenda says probably best to ask what's the best one for your purpose as the best deal probably changes.
