Australia banned telemarketing a while ago, it worked pretty well. The only spam phone calls left are 100% illegal scammers. https://www.acma.gov.au/telemarketing-and-e-marketing they give out million+ dollar fines which sort things out. Just being a customer doesn't allow them to send marketing, you have to opt in.
It's the year 2026, I refuse to believe that phone companies cannot figure out who is a scammer and who is not.
Also, getting SMS from email addresses. Nobody asked for that feature, please nuke it.
