I’m curious whether this is an RRC/IMS stack issue on Samsung’s implementation or something carrier-side in Australia’s 000 routing setup.

Emergency call handling tends to expose edge cases that normal calls never hit. Would be interesting to know if this affects only certain models or firmware branches.

Indeed. It now has been revealed even telcos were not doing real world tests https://www.abc.net.au/news/2025-10-08/surprise-drill-for-te... and new laws were passed this month that they must make it possible for an independent university to do testing https://www.acma.gov.au/articles/2025-10/acma-strengthens-in...

What's the difference with emergency calls? (I know nothing of this.)

I don't know how it is with VoLTE and other recent things (it may be the same; it may be different), but at one time in cellular world: Emergency calls differed from other calls in that they Must Always Work.

An emergency call can connect using any tower that is compatible with the caller's hardware -- with or without service provisioned, and with or without any sort of SIM.

Need help, and find a dusty phone somewhere? Turn it on, call emergency services using 0118 999 881 999 119 725 3 [*], and if there's any cell service within range that it is physically capable of chatting with then the call will go through.

It will kick other users off if that's necessary in order to allow the emergency call to happen.

There's nothing to bill, so there's no billing systems (or even billing logic) to get in the way either.

It's intended to always work.

		I'm scared of this. In my country, at least on my Samsung Galaxy mobile device, they are sending Flash Messages for ads, even though I requested to be removed from their lists (and they complied... with calls and SMS). I already see them making use of this for ads until a big group of people complain. I'm tired, boss.

Namely the fact that emergency calls can be routed through other networks that aren’t your own (in fact, you can place an emergency call without a SIM).

You can also make emergency calls when you don’t have enough signal for regular calls.

It forces it through
