I have a question, what do companies do with your phone number ? can they trace who you are and what you do ?

How do you combat this sort of thing? Besides periodically changing your phone number, of course

Obviously, never enter your real number in a web form unless the service depends on you getting called back ... in which case you likely would have called the company by phone anyway.

This is not possible.

Most services that require a phone number also verify it via sms.

Additionally they check so that each number can only be used once, disabling most free sms receivers online.

Oh, i never experienced this. My thought is rather, "nobody will call anyway" ... that said, perhaps it's because i'm largely living outside of online buseness. Location: Europe mostly. What busenesses are you talking about, out of interest?

they're talking about sites like Facebook or Google

I tried random numbers and internet numbers with Openai, Wolt and Revolut.

They were all rejected
