> The Nokia 5110 is a 2G telephone, meaning it uses the original 2G mobile network to communicate. This network has long been decommissioned in most western countries, including Australia.

They do but most won't be able to use a phone this old on it. Reason being the SIM application was taken out of the issued sim cards years ago for T-Mobile (something like 6 years or so at this point). Newer 3G-era cellphones use the USIM application and can fall back to the 2G network.
So the only way to still use a device that's pre-3G (circa-2007 or so) on the 2G network is to have a SIM that's been activated the whole time. T-Mobile will not activate expired SIM cards that still contain the application.

EDIT: Funny thing about 3G-era phone support, you can use a euicc (removable ESIM) on a phone from 2007 (I used Sony Ericsson K850i) and it will work just fine with an activated esim to access 2G.
