Welcome to 'Is this Phone Blocked'

With this policy change you can now no longer use any device you want from any provider in the world, even if it may work perfectly! (Including for 000 Calls)
Phone not allowed for voice Android 9    Sim not allowed Android 12
The telcos now get to be judge, jury and execution, solely deciding what phones you are allowed to use and where you must have purchased them from.
Even phones that support Voice over LTE & 000 Emergency Calling on 4G have been blocked, and the telcos refuse to unblock them!

This site allows users to find what device models are blocked and 'supported' on each Australian carrier network and find a list of phones affected by 3G shutdown.
