Two factor based on SMS is known to be hackable.? Email is possibly safer,
depending on your provider.? OTP systems or apps are a
way more secure way to go.? I notice Microsoft and other companies now have
multi-factor authentication with a choice of adding
several different ways.? Passkeys might be a good idea if big companies didn't
insist on making users store their secret keys in
their clouds.? Grrrr.? On the other hand passkeys in the hands of non-tech
users is probably a disaster waiting to happen.
> I also hear(experience of Users) ISP ownership is being consolidated.
It's clear Australia needs decent anti-trust legislation with teeth and has for
some time.? Over a range of industries.? Decent
control over mergers and acquisitions.? Also a way of forcing oligopoly
companies to break up.? Maybe some sort of tax punishment on
very large companies.? Is it going to happen?? Not when those giant companies
keep donating to politicians or running Murdoch style
scare campaigns.

I did a Google web search to see if I could make a voice emergency call
to Triple-0 using a Telstra data only Sim card. Depending on the wording
of the question Google AI said yes, or no.
When I did this search: "Emergency call on telstra data sim", Google AI
said yes, I could:
"Yes, you can make emergency calls (000 or 112) on a Telstra data SIM,
even if it's a data-only SIM and doesn't have a phone number"
However when I searched on "use telstra data only sim for emergency
call", Google AI said no, I couldn't:
"No, a Telstra data-only SIM cannot be used to make emergency calls
(like calling 000 in Australia). Emergency calls require a voice
service, which is not included in data-only SIM plans."
The latter seems odd, as you are supposed to be able to make emergency
calls without a Sim card.
This came up as I have been using a wireless modem. Recently I bought a
new modem which an RJ-11 socket for an old fashioned analog phone. This
works fine with my phone Sim card. But I thought it would be useful to
be able to be able to make an emergency call using the data only Sim I
normally use in the modem.

Your phone socket probably is a VOIP phone so who knows.? Is it possible to
make 000 or 112 calls from a VOIP phone?? BTW Did you
actually try it?

The modem is configurable for VOIP, or voice over LTE (VoLTE). I have it
set for VoLTE, which is what you are supposed to use now for mobile
emergency calls.
> BTW Did you actually try it?
No, I can't call the emergency number unless it is an emergency.
Which I have not had to do since April.
