Re: texst to a landline

   Yes, but as far as I know there's no such option. Though
it could be handy for situations where companies insist on
a 2FA code. Many are happy to send it via email, but at
one point I was considering opening an investment account
and I couldn't sign up without a cellphone. They won't send
codes via audio. I suspect that they just want the cellphone
number and to get people using apps, so that they can track
their customers and perhaps sell personal data.
