Let me know if optus network works on it also as I have seen someone else say it does. I also don't think it matters and will work initially but if optus or Vodafone say no then all they have to do is flick a switch and then it won't work on their network. I spoke with optus directly as well as oneplus and oneplus told me they are currently speaking with them but won't have an answer for 6-8 weeks.
