This wikiHow teaches you how to block calls from anonymous numbers on your iPhone or Android. You can do this by using Do Not Disturb on your iPhone, or by changing call settings on your Android if you have a Samsung phone. If you don't have a Samsung phone, you can download an app called "Should I Answer?" to block incoming unknown calls on Android. Unfortunately, there isn't an app or a setting available on iPhone that will only block incoming private, unknown, or restricted calls.
Steps
On iPhone

4Tap Allow Calls From. This option is near the bottom of the screen.
-
5Tap All Contacts. Doing so will select your entire contacts list as the exception to Do Not Disturb. You will no longer receive calls from people who aren't saved in your Contacts app.
- This method blocks calls from any numbers that aren't saved in your Contacts app, meaning that you might miss out on a work- or appointment-based call.
- Do Not Disturb also prevents other app notifications (e.g., text messages, email, social media) from showing up as alerts.
On Samsung Galaxy
-
1Make sure that you have a Samsung phone. Samsung phones are the only Androids that have an anonymous caller rejection setting.[1]
- If you're using a non-Samsung Android phone, skip ahead to the Should I Answer app method instead.
-
2Open the Phone app. Tap the phone-shaped app on your Android's main screen.
-
3Tap ⋮. It's in the top-right corner of the screen. A drop-down menu will appear.
-
4Tap Settings. You'll find this near the bottom of the drop-down menu.
-
5Tap Block numbers. It's in the middle of the menu. This will open the call-blocking settings.
