[If people think this thread is not enough Linux-specific, maybe
we can move it to luv-talk.  For now, I'm going with the flow,

Yeah.  Does anybody know how the telcos make this determination?
Clearly, they're not assessing live the actual technical
capabilities of the phone, as shown by my experience "your
device is not a mobile phone".  Presumably, they're looking up
in some (incomplete) database of phone models.  But how do they
make the link between the phone in my hand sending that SMS and
the phone model?  Is it via the IMEI, and there's some global
database relating IMEIs to manufacturers' models?  Or is somehow
in the handshake between the phone and the network when it first
connects?

This whole thing has not been thought through well at all.  Just
some things that come to mind:
- What if SIMs are swapped among various phones?  Is service on
  that SIM cancelled if it's temporarily in an "unsupported"
  phone?
- What if an Australian SIM is internationally roaming?  It
  seems nutty to cancel that service because it can't call
  Australian 000.  (Emergency calling when roaming seems to be a
  very messy thing.)
- What about a phone used only, or primarily, for data?  Sure,
  there are data-only SIMs (in passing: how are they affected by
  this regulation?).  But often the cheapest way to get data is
  just to sign up for a data-competitive phone plan and just
  ignore that it can also provide phonecalls.
Admittedly, these issues probably affect only a minority
of phone users, but an important minority, especially for
innovation.

Well, yes.  And that's really alarming.  All the more reason for
taking what action we can, like signing that Change.org
petition, making an ACMA submission (deadline this coming
Tuesday), and writing to our Federal MPs and Senators.  At the risk
of being annoying, links repeated here.  I feel that this is
important, especially for FOSS people like us.

Not only the carriers, but the entrenched big-name mobile phone
brands, who are pretty cosy with the telcos.  They also want to
suppress competition.  And I'd say it's a calculated stealth
monopoly by creating anxiety that if people don't buy a
telco-peddled phone they'll be "unsupported".

Pushing people out of fear to buy really unneeded new phones is
also bad for the environment from an electronic-waste point of
view.

As with so many things, what we need are solid, impartial,
strong technical standards.  Unfortunately, governments tend to
be captured by rent-seeking corporations.

My reading of the ACMA Determination is that for a foreign
traveller it's not about roaming per se (when the customer
relation is with the foreign provider), but about when the
traveller purchases a local SIM.  It seems the traveller could
use it only for 60 days on an "unsupported" phone.  And the
Determination itself says in part about the exception:

   .... the mobile phone is being used by a foreign traveller in
   Australia who intends to remain in Australia for a period of
   time which is less than a specified period of time....

Since it's based on intent, it seems a rather squishy concept.
I doubt that would have much effect on the telco's business.
But maybe your reading is different.
