When I get a block number id call from someone how do I know who called me?

Is it impossible to know who called me if it's a blocked number id number btw I have a iphone and live in the uk

Short of making a request to your service provider there's no way you can tell. One way to handle this is to bar calls that with hold their numbers or forward them to a message asking them to call from an un-hidden number!

Perhaps you can block people who don't display their number. Here in the US landlines announce you have dialed the right number but the party doesn't accept calls from blocked numbers. If they want to talk to me they can't use their caller block feature.

  • What happens when you block someone on an iPhone 6, and they text you or call you? Specifically, does the phone keep ringing or does it say the call can't be made? Does the text deliver and just never show up on the receiving phone, or does the sender get a message saying the text can't be sent? (The other phone is not an iPhone.)
  • What happens if you block someone and they attempt to call or text you? I have a Verizon 4s iphone. I recently got the ios7 update and it comes with an option to block contacts. What happens if I block my ex and he tries to call me? Text also? Will he be notified that I blocked him? Or what happens?
  • Someone called me on blocked number? I have an iPhone 4s it came up "blocked" as where the name usually is then underneath it said unknown What does this mean? Does it mean the person blocked my number? I never blocked anyone
  • SOMEONE CALLED ME ITS UNKNOWN CALLER HOW DO I CALL HIM/HER BACK? Okay so i think someone is pranking me i dunno who the *** is he.but. I just wanna call him back. And know his number to make sure he's one of my friends? But i can't call him back and i can't see his number because on my iphone 4 which i'm using doesn't come with a display name. So everyone who calls me is unknown is there a way that i could call them back or maybe get their number
