Me too , at first I thought it was my little brother . I think they are probably numbers from collection agencies or sales that have gotten several complaints.

Yes I do and I also get, "Telemarketing". I never answer any of them. Sometimes they will leave a message.

I use Google Voice and T-Mobile.

Yes I have I answered anyway that just happened about a week ago first time I have no idea what's going on I did block the number afterwards and message.

Not yet....yikes!

No, our carrier does not give such notifications. Does any carrier do that?

If you don't recognize a number it could be a scam to connect to your computer or phone. Happened to me the other day. Google scam area codes fora list of codes scammers use. Received a message from dating site Meetmindful.com to text someone. Then follow up phone call. Be careful everyone.

Yes. Just hang up. And if asked a question - never answer "yes" - again hang up immediately.

For me it's easy now, as I still have a landline and answering machine. if an unrecognized number comes up, I let the machine answer. If it's a scam, or robo-call,, no message will be left !

If I am in the right mood and scams call me I will mess with them. That might be a feature on your phone.
