Do you want to know how to block hidden calls on your landline or smartphone, iPhone or Android? In this guide, we detail the procedure to follow, step by step.

Many landline or mobile phone users regularly receive unwanted calls. This often involves solicitation, but it can be much more serious. Telephone scams and premium rate numbers are becoming more and more widespread. If you too are tired of receiving calls from unknown numbers, and you no longer want to be disturbed, know that there are several solutions to put an end to this type of nuisance and block a phone number.

How to block hidden calls on iPhone?

Previously, iPhone users did not have the ability to block or reject hidden calls. They were therefore forced to switch their phones to “do not disturb” mode to no longer receive calls for a given period of time. However, this option blocks all their incoming calls, even the most important ones.
Today, it has become possible to automatically reject hidden calls on new versions of iPhone thanks to the activation of the “Silent stranger calls” option.

This function prevents you from any inconvenience in the event that you receive a call from a hidden number. It can be activated by following these steps:

  1. Access your “iPhone Settings”
  2. Tap the “Phone” section
  3. Look for the option “Silent unknown calls”
  4. Click the toggle switch to activate it

Your changes will be taken into account automatically. This way, hidden calls will be sent directly to your voicemail. And, you will be able to find them in the list of your recent calls.

To unblock unknown numbers, simply repeat the same actions by clicking the toggle switch a second time to deactivate the “Silent unknown calls” option.
