No caller id on iphone?

I been calling this person on no caller id on iphone it was ringing few times first then i called again and it went straight voicemail how comes? Because they can't block no caller id

Could have turned their phone off

Actually they can block just by ignoring your call the first time and rejecting your call the second time. And there are apps that allow you to call block, takes less than a min or two to download and setup.

Most people see a number they don't want to talk to or UNKNOWN and let it ring and then reject it, so it does not go to voice mail. If the same number or UNKNOWN show up again, they just reject it on the first ring and it goes to VM, especially of they are on a call or in the middle of a texting conversation.

No, Iphone does not use it

  • Why is my iPhone 4 changing around caller ID pictures? Recently my iPhone has started changing around the caller ID photos of my contacts. Not sure why and wondering if it might be a bug? Has anyone else had this problem and is it something to worry about?
  • When you Block Caller on iPhone, does it completely block them or do they show up as Unknown? I routinely "Block Caller" telemarketers, so does using the iPhone "Block Caller" option block all calls, or will the calls still come through and just show up as "Unknown"? I've received a lot of "Unknown" phone calls lately, so that's what I was attributing it to.
  • 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.
  • Is there any way i can change my text caller id on iphone? So as we know we can change caller id using apps, when you call someone on their phone it displays another number… I wanted to know if i can do that on messages, like i send a message but the other person gets it from a different number, the number which i changed to, iss there any way to do it… I have a jailbroken ihpone3gs
