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

        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?

          Yep. I’ve tried using dummy numbers in the past for things where no phone contact is required for contact and it frequently triggers fraud prevention even if not rendered useless by sms verification before submission.
