I’ve had to allow messages and calls from unknown sources on my plane my whole life, but I’m starting to think that with all these data breaches it would be the best course of action to block anyone I don’t know. I get so many scam/spam calls/messages now.
I’m not sure how this works with calls and texts you’re not expecting though. From couriers, doctors, car dealerships etc.
I know people that do it, but it seems onerous to keep on top of.
