Methods to block or avoid No Caller ID calls 

From now on, we will discuss the methods to avoid or block such disturbing calls. There are various solutions like you can use a particular app to block such calls but the problem with such apps is that spammers or hackers eventually find a way to bypass or break such apps and again you will start getting calls with no caller id.

First, we will show the three best ways to block No Caller ID calls on your iPhone then recommend some efficient apps as well for the given task.

First Method: Do Not Disturb Feature

It is one most useful features of the iPhone, through this method the number unwanted calls from telemarketers, private or no caller id calls can be effectively reduced. Before enabling the Do Not Disturb feature on the iPhone you have to do some configurations like you have to allow all the numbers from your call list to go through from voice mail because most of the time no caller id calls do not leave a voice message.  

Follow the given steps to enable Do Not Disturb feature in your iPhone:

  • Open setting in your phone 
  • Select the Do Not Disturb option
  • Select Allow calls from option 
  • Then select the All contact option from the menu

The Do Not Disturb feature is enabled, now only the numbers stored in your contact list can call you directly the rest of the unknown calls including no caller id calls because it is not stored in your device.

The disadvantage of this method is if anyone known person calls you from the different number the cell automatically bypasses it to voice mail hence you don’t even know about the call unless you check your voice mail inbox. 

So you have to check your voice mail inbox from time to time to ensure that you haven’t missed important calls.

Second method: Using Contacts 

So what if the same person is disturbing you over and over again, so you can assume that spammers are using the same number, again and again, so to tackle such circumstances use this method and follow the steps mentioned below:

  • First, you have to create a new contact
  • Open contacts 
  • Press the create contact 
  • Then press + option 
  • Enter 00000000000 (or any random number) as contact number 
  • Press the done (you stored the No caller id in the contact list)
  • Again go to the contact list and select the no caller id number
  • Then find the option block number in the menu
  • After selecting the block number option, the message will be popped up that number is blocked

The problem with this method is it is only effective against only one number if you are receiving masked calls from different organizations or people then this method requires to create contacts for each separately. 

Third Method: Cell Phone services (Network Level) 

This method or solution is provided by the network carrier companies and almost all carriers over the globe provide such service but some of them provide it free and some charge their services. 

This is a very useful method. By using this you can block no caller id on the network level, ever carrier uses different methods to enable this service here common steps are:
