If having a phone number has no benefit and only brings spam, and WiFi is ubiquitous in urban areas, a huge chunk of the population don’t really need cell plans any more. And the places without WiFi coverage (less dense areas) are the most expensive to provide service.
In the US at least, the FCC used to be pushing hard to combat the spam, like requiring authentication for caller ID, and it was the carriers that were dragging their feet and lobbying against it. So something tells me they just continue to view all the spam senders as an easy income source and don’t mind letting their whole business model die if it means short term profits.
That is I don't think people will use WiFi only, unless they are going to drop always reachable communication. (which given the SPAM OP mentioned maybe...)
This is a "flash SMS" message: https://nickvsnetworking.com/flash-sms-messages/

Android just gives you a generic popup that says "Class 0 message" in my testing.
One time, I picked up, and it was this seemingly incredibly rude person who sounded real but continue talking in a pushy manner without stopping despite what I said.
It's insane getting so many calls all the time like I owe them a bunch of money or something. Anyone else get this?
The US seems to have completely given up on protecting its public phone network against abuse, while at the same time relying on phone numbers as the primary identifying key and authentication method for humans in countless business processes.
It took years (if not decades) of regulatory neglect to get that bad; I doubt there’s an easy fix at this point. It’s really concerning.
And what's worse is that even if this were to be fixed now, the reputational damage is already done, since many people will probably never change their devices back to ringing again.

My US mailbox is full of spam calls.
Curiously, it seems to have become a cultural touchstone not to leave a voicemail. I have had to educate people about this. My service is with Verizon, and for what I assume are historical reasons the caller will hear rings on their end even if my phone isn't receiving the call (AT&T does not have this issue). If you don't leave a voicemail, I literally have no way of knowing that you called. Said voicemail can be as simple as "call me".
I'm a physician, and the hospital where I do most of my work has a policy against sending PHI over text (a very reasonable policy). So many nurses are reluctant to text me anything, even when it's just "please call Adam on 3 South".
WhatsApp here in India has so much spam now. With ads, I am starting to think these spam are just ads sold by WhatsApp.
Probably so-called SMS flash messages. They're shown as overlay popups on Android too.
