unknown caller to my cell phone. I do not answer unidentified phone calls. They tend to be con artists or telemarketers. If they don't leave a message, they didn't deserve for me to answer the phone.
MrNumber phone app identified it as a probable telemarketer and dumped the call. I don't find information online, but I suspect MrNumber is probably correct.
Just take these numbers and save them in your Contacts as SPAM. Then route all calls to SPAM straight to voicemail. No rings to bother you and they will never leave a message. Problem Solved.
And if you see one crossing the street, you know what to do.
These people called me in March, and again today.
I didn't answer then, but did try to answer today.
Either they hung up or I picked up too late today.
Gotta be a scam.
