I got a phone call from +1(1)and it seemed weird. What could it be.

With CallerID Spoofing, the number shown can be anything the caller wants it to be. Usually, these calls are trying to identify something (modems, fax machines, voicemail box, etc.). Its hard to know exactly what this particular one was, but often they are not harmful but just annoying.

  There’s an App called “Hiya”. It tries to do some checking of the incoming number and x-ref it with known scammers. It will even do some blocking for you if you set it up.

Also if you get a call from +1(1), it is definitely from the USA. Sometimes such calls cost you money and can be a scam. Therefore. Such calls should not be entertained.
