5 Easy Steps to Unblock Unknown Incoming Calls on OnePlus 12

In the age of smartphones, it’s essential to have seamless communication. However, certain circumstances can prevent us from receiving calls, including unknown incoming calls. OnePlus 12 users may face this issue due to various reasons. If you’re one of them, this guide will provide you with comprehensive instructions on how to unblock unknown incoming calls on your OnePlus 12. Follow these steps to restore your phone’s ability to receive all calls, ensuring you don’t miss important communications.

Before proceeding, it’s crucial to check if the Do Not Disturb (DND) mode is activated on your OnePlus 12. This feature silences all incoming calls and notifications, including unknown numbers. To disable DND mode, swipe down from the top of the screen to access the Quick Settings panel. Look for the DND icon and tap on it to turn it off. Once DND mode is disabled, proceed to the next step to unblock unknown incoming calls.

In addition to checking the DND mode, you should also verify if you’ve blocked the unknown caller in the past. To do this, go to the Phone app and tap on the “Contacts” tab. Select the “Unknown” contact from the list and check if there’s a block icon next to their name. If the number is blocked, tap on the icon to unblock it. Now, unknown incoming calls from that number will be allowed to come through.

To check if you have accidentally blocked incoming calls from unknown numbers, follow these steps:

Open the Phone app on your OnePlus 12.
