Called & left no message. Only says United States.  Prefix starting with a one is shady anyway. Blocked!!!

Got this call twice on my (suburb of Dallas, TX) cell at 11:20 and 5:30. Didn't answer either time, but plugged number into "Whitepages" app. Result was "Invalid phone number. Reenter valid phone number and try your search again."
Have received 26 calls with various numbers which I have put in my phone's contacts and named all *BLOCKED, and
enabled "Block this caller" option at bottom of contact page. At least those are call numbers I won't be receiving again!

Called my 90 year old mother telling her she qualified for free back surgery.

Called twice yesterday. CID says United States. Didn't answer. No message. Blocked.

My caller ID had the number twice.
