If I block a caller in my iPhone 5s, will they know if they try to contact me in any way?

If I block a caller in my iPhone 5s, will they know if they try to contact me in any way?

If you block they can't call you back unless they track the phone block means you can call them but they can't call you but be careful some people will track the iPhone I hope this helps

  • 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.
  • 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?
  • 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
