Trying to conceptualise the best way to utilise two phone numbers as a fail safe security for sms verification issues.

I know i know, nothing is likely completely secure. And im' probably not clear on what PROBLEM there is that needs solving.

The easy part, i get a second sim, with a second number. I give that number out when needed so *not* every Tom, Dick, and Harry has my number now. But i can still be reached via it easily. Most of the BIG companies could possibly still get to use my main number, lesser ones or just apps …
