Asking for a friend. What are the possible reasons why someone would get multiple calls on their mobile number in the 12am to 2am time slot, from a number with all zeros? I.e. 000-000-0000. 14 calls in a two hour window. Scammers? Prank caller? Stalker? All of the above? It’s totally silent on the other end. I’d appreciate any input and speculation, thanks.
that is some stalker/horror movie shit right there. call the cops and/or an exorcist. Burn your phone in the fires of mount doom.
@Alphu#91466 haha. good one. my friend isn’t freaked out though, just annoyed more than anything. My guess is someone familiar is messing with her. These calls happened last night. We’ll see if they happen tonight too.
I have received similar calls. They hang up if they do not detect a human voice (or probably any sound), and to trigger the detection you have to speak at the correct time, its a rather rubbish detection method, if you speak too soon, its not detected, if you speak too late its, well, too late 
In my case, the calls came from “Maicozovt”, and its what got me in to scam baiting.
@JoeHimself5#91464 I think it displays 0000000000 when you call using GlobePhone. I tried it once and it showed 0s.
Thanks for the feedback, folks. Only one “zero” call came in last night. Hopefully it trends down to zero.
