Wireless Telco: "Telstra also warned last month that older,
non-upgradeable Samsung devices could fail Triple Zero calls
Which can be less of a problem if there are full-digit emergency numbers that could be saved as a contact (preferably quick-dial).
Auto-call routing can fail if you're on one side of a regional border but are connected to a cell on the other - and local EMS can't forward calls to the neighboring EMS (or just suck at it).
I used to live on a border and local EMS was 3-digit only. The only way to call the correct EMS was to call their non-emergency number and get forwarded - but only after getting scolded first for not calling the 3-digit number.

I think there's a lot more code running on SIM cards these days to reduce/prevent that. On my Canadian Rogers phone, when I do a network scan, I don't see the american networks at all, but then when I put in a foreign SIM, they light up. Similarly, it can take a while of driving into the US before it detaches from the Canadian network and finally hands over to the US.
It was actually an issue with my French SIM that was supposed to work in Canada and USA: it REALLY wanted to connect to the US networks, even though I was ~10 stories up in Toronto and very occasionally getting an SMS through once an hour to the US network.
