How so? No blow-ups in the decades I’ve been doing it. People are not obligated to be voice-reachable (at least not by any laws I’ve encountered). Creditors need to send you a bill, sure, but that’s their problem. If they can’t handle fax they better be willing to use snail mail.
What’s blowing up in people’s faces is the culture of sharing a mobile number that then takes the role of identification, which then gets exfiltrated by cyber criminals. The abuse of using mobile numbers as an identifier has spread through Europe and only a small segment of privacy advocates currently realise the problem.
Twitter demanded a mobile number from me. Would not take a fax number. So I walked. Shortly after, Twitter had a data breach that leaked everyone’s mobile numbers. Then Twitter was caught abusing the mobile numbers themselves in ways not allowed in the privacy policy.
Americans are extra fucked because there is no privacy safeguard. The bank shares the number with the credit bureau, who then shares it with all members (banks, insurers, etc) and those who will pay for it.



Generally I would expect in france to be able to get a prepaid SIM for €15, which would then last a year. Is that not an option?
I would still object to paying anything, and then being forced to tend to that number which pinpoints a geographical location. If they can get msg to you by sms or voicemail, that likely satisfies any obligation they have to inform you which then creates an obligation on you to monitor the phone (I suspect).
