Seriously, #Australia's #2G & #3G #Shutdown and [www.youtube.com] #IMEI-based #Blocklisting WILL inevitably kill people
And the only "tool" there is is #Telstra's Website [www.telstrawholesale.com.au] and just teting random IMEIs [github.com] only yields two possible results:
'We don't know this device at all'
"'We've not blocklisted it'*
Even when testing it with obvious #2Gonly & #3Gonly devices that certainly don't support #VoLTE...
Seriously, there's a reason why every other nation at the very least keeps the absolute minimum of bandwith necessary to maintain #2G & #3G service for #EmergencyCalling.
In fact, #Germany learned the hard way that [en.wikipedia.org] #CellBroadcast and #PTY31 / #RDS - based #alarms and #sirens are not replaceable.
