Q: How to block" No Caller ID " call from my iPhone

no, as no number is associated with the call for it to be blocked.

I agree.

Not on the phone itself but most cell carriers have a feature to block these calls.  Check with your cell provider and you may find that it's already a service that is part of your calling plan and they can simply enable it for you.

you can block all numbers not in your contact list by doing this:

1. go to settings
2. open "Do Not Disturb"
3. slide on "Manual"
4. tap on "Allow Calls From"
5. Select "All Contacts"

All calls from numbers not on your contacts list will now be blocked. You can however still see all numbers that attempted to call you as missed calls. Verify the numbers and if legit, add them to your contacts list to receive any future calls from them.

sprint does NOT.

they say op-in your contact list but then that blocks all new people. :-(

that doesn't allow calls from new people :-(

if we can *82 ourself there should be a way to block others!!!!!!

Sprint is also being sued by the FCC for "cramming" cell phone bills. It's not a company I would ever do business with.

Thanks heaps mate, No ID call stopped!:)

Thanks for that tip! Do you know if numbers not on my contact list will go to voice mail?

Thank you.

I wanted to add that according to Verizon chat they are working on an app that will allow "no caller id" to be blocked. They suggested to look for apps in the meantime, but unfortunately I do not trust most of them. - just my opinion... no justification, just over cautious is all.

The "aid" suggested within this reply is DANGEROUS.

Reason: The calls are not blocked, they are merely silenced.

That means: If e.g. an unwanted person calls you, they will still get through and only get the impression that you simply do not answer the phone.

In the case of patient hard-case type callers (e.g., stalkers, ex-girl/boyfriends etc.), this can actually further agitate the caller and motivate him to pursue further means of contacting you (e.g. paying people a visit, sending receipt-requested letters etc.).

In contrast: Blocking unwanted callers through the standard iOS blocking feature immediately cancels ingoing calls, giving the impression that your number is disconnected / not available, which would be the expected & desirable behaviour.

Interesting that you chose a year old post to respond to. All ways of blocking on the phone have this problem. The ONLY way to truly block a number is to block it at the carrier's network, before it gets to the phone. Once it reaches the phone any blocking method will just ignore the call. Most carriers offer blocking at the network level, so in the situation you describe you should use the carrier's blocking capability.

I kept getting calls from NO Caller ID. I don't want to limit calls to just my contacts list. So to block this type of call:

Create a new contact called something like Non-Caller or No-Caller

Enter 000-000-0000 for the phone number.

Scroll down and select Block this Caller

This should stop calls from calls that come from "zero" numbers.

If you want to know who you are getting a call from when it says "Unknown Call" you can go to www.trapcall.com and sign up for their service. They have three different pricing plans. As of now I think it's $4/$8/$20 per month. This will remove the "unknown call" feature and actually show you the phone number. It enables you to blacklist the phone number and record their calls. Handy if you are getting harassed by telemarketers and you need to report them.

These were the instructions my carrier gave me.
