I'd buy that for a dollar! (plus a SIM plan)
Crazy price for a budget phone.
I believe this is locked to Optus. Black and Blue available.
Amaysims' product page don't have detailed specs so check Oppo's official site
Spec page
Optus branded phones also $1
Optus X - X Pro
Optus X - X Go
Optus X - Sight 2
Optus X - X Lite 4G
That would be amazing :)
