I remember an old Android crashed or something. Maybe it still carried that bug?

What happens if I don’t act?

Under the Government’s Emergency Service Call Determination, all mobile network operators are required to block devices from their networks that are not configured to access emergency call services. If your device is on the list of impacted devices, you will have 28 days from when we notify you to update the software or replace your device to stay connected to the Telstra network. After this time, the device will be blocked from accessing all Australian mobile networks.

Can I still use my phone on my home Wi-Fi after it is blocked?

Yes. Your phone can connect to a Wi-Fi network for data purposes only. However, blocked devices won’t be able to make or receive voice calls over Wi-Fi, including emergency calls, or send and receive SMS.

For example if your phone only makes emergency calls over 3G and the carrier shuts down 3G, then you will be unable to make emergency calls anymore.

If the OS doesn't recognise it as an emergency number then it may fail the call if it believes that whatever network it is associated with won't connect it ("No service" vs "Emergency calls only" indicators etc if you are out of coverage from your SIM's network but within range of other networks).

Emergency calling is supposed to work over any network (even without a SIM card inserted, much less an activated, registered, associated one), but only if the OS tries to dial it as an emergency call.

Some handsets do not connect to secondary networks for emergency calls without the update that fixes the problem.

Emergency calls often aren't just normal phone calls. At least in the US, they're required to transmit their location to the operator, and this is the case in many other countries as well. I doubt the technologies are standardized.

This is explained if you click through the link to the Samsung post about this issue.

> Australian mobile operators and Samsung have identified a number of older mobile devices that will not correctly connect to an alternative mobile network to make Triple Zero calls when the customer’s primary mobile network is unavailable. These devices need to be updated or replaced to make sure they work reliably in an emergency.

Is this puffery or not? I don't know, IANAL, but maybe? I checked and Puffery is legal in Australia. https://en.wikipedia.org/wiki/Puffery

Chances are there will be securities fraud case. Where they will refer to statements such as these and the fact that it wasn’t really the case. https://www.bloomberg.com/opinion/articles/2019-06-26/everyt...

I only just stopped using my HUAWEI P20 Pro - which I bought in 2018 - the phone was still great and handled everything I needed it to - plus the camera was amazing. I just got a new phone as the battery life was getting silly and it began restarting all the time - and I'm not loving it compared to the P20 Pro.

I think a 7 year old phone has no reason to not be suitable to 90% of what people want from a phone (in my case it was 100%). Frustrating to see them abandoned by manufacturers.

The fix is just a software update for that phone, it's not on the replacement list.
