What level of SIM privacy can be achieved in Australia? I haven't seen this talked about anywhere so I thought I'd ask the question.
I've read Michael Bazzell's books where he suggests to buy a pre-paid SIM with cash for data, and use VoIP for legacy calls.
Unfortunately, you can't purchase a SIM or phone number in Australia without your ID. Including a VoIP number.
I've also seen Silent Link thrown around a lot, but they are quite suspicious. They make connections to Israel (as well as other countries), and with a no-number or data-only SIM, you still get assigned a Polish number, which in actual fact, makes you stick out like a sore thumb (especially if you're using it for months or even years).
So, my question is, is this something to even pursue in a country like Australia, especially if you're just an average person? I've moved all conversations with family/friends to Signal, and to counter approximate location tracking, I have aeroplane (airplane) mode enabled 24/7, unless I need data (rarely). If I need to make a call, it'd happen over Wi-Fi calling, unless it is not available.
Thanks.
