Telstra and Optus will delay the planned closure of their 3G networks in order to conduct a final public safety awareness campaign amid concerns that emergency services calls and medical devices could be affected.
Consumer phones in regional areas are still an issue.
As @baku said, 3G has better range than 4G (which has better range than 5G).
If someone in the middle of the bush, or on a country road needs to use their 5G phone, they may not have coverage.
I have a friend that had to drive 10km with a cracked skull, ribs and broken arm and leg because he didn’t have coverage on his farm. He now has 3G coverage, but not 4G.
