You get actual humans calling you from unknown numbers? Lucky! I only ever get "Chase" from "Home Security Solutions" or whatever.

Yeah, recently I've had quite a few legitimate ones, mostly having to do with home renovations or other transactions.

I like most am deeply unsatisfied with the archaic system though of a basically unchangeable 10-digit number granting permission for anyone to fill up my phone with messages and interrupt me with calls, and hate that I have to ever answer calls from a number I don't know.

I really would like a mutual opt-in system, where you have to pre-establish consent before it's even possible to message or call you, but it seems impossible to get there from here. We can't even get the stupid cell phone companies to strongly enforce that caller ID isn't spoofed!
