Is no caller id a number you blocked?

I have an iphone 7 and recently blocked someone. I think he called today because no caller id called me two times 10pm and then no answer from me so again at 10:01pm. It the same way the guy i blocked calls me if i don't answer the first time he try again one more

Yes, and no. Sometimes, when you block someone, their call won't come through period. When someone call with no caller ID they may have put some additional numbers in, while dialing your number so that way you won't be able to see what number they're calling from.

  • What's the difference between an 'unkown' caller and 'no caller ID'? This unknown number keeps ringing me, and i thought if someone blocked their numbers (on iphones) it comes up as no caller ID so i'm not sure if it is still a blocked number or a number that can't come trhough. But when i answer nobody speaks and they've rang one of my friends so its not a scam phone call also they don't speak at all so if it was a company of some sort they must of spoken so its probably a prank call but i wanna know the difference to make sure.
  • Unknown caller a blocked contact? I have 3 of my contacts blocked on my iphone 4s i0s7 and when i first blocked the first 2 i kept reciving Unknown calls, Now today 4 weeks after blocking the third contact i receive a unknown call and when i pick up the phone line is dead then they hang up. Are these calls coming from the blocked contacts or just something else?
  • IPHONE-when I make a phone call I can't hear the caller and the caller can't hear me? When I make a phone call I can't hear the caller and the caller can't hear me. Also, when i try to put it on speaker, it goes off speaker in a couple seconds. I can't even hear the dial tone or the voice box if a person doesn't answer. - my volume is all the way up - i don't have my phone on do not disturb or airplane mode
  • Iphone Caller ID-Will my contact see my number if I turn caller ID back on? If I turned Caller ID off on iphone, called someone from my contacts (and they have me in theirs), and then turned caller ID back on and they have me in their contacts, will they see that i called? Like will they see in their list of phone calls my name, or no caller ID?
