Have been getting calls from 999-999-92114. That is not a mis-type. It’s a phishing scam. My cell phone doesn’t ring unless the number is in my contacts list.
I see on the handset numbers and sometimes cities (lately they’ve been coming from different places in Washington state - I’m in TX). I just let the voice message take it if it isn’t someone I know. And if for some reason I don’t recognize a number of a person or service I want to talk with, I figure they’ll leave a message.
