Blocking unwanted calls and messages
How to block unknown calls
When receiving calls or messages from numbers that you don’t want to encounter again, you can add them to the blacklist. The blacklist function allows you to customize any phone number you want to block.
To block calls from outside your contacts using the Blacklist function, follow these steps:
Step 1: Tap on the gear icon in the top right corner of the screen. In this menu, you will have many different options such as private numbers, unknown numbers, similar to the illustrated image below. Since you want to block calls from outside your contacts, select the “Unknown numbers” option.
Step 2: Then click on the plus sign (+) to add the phone number you want to block. The system will also ask you if you want to block messages or block calls. Simply check the box to choose the method you want to block.
Blocking calls from outside your contacts on iPhone
On iPhone, you can easily do this
Step 1: Open your phone and access the “Settings” app on the screen. Then scroll to the “Do Not Disturb” category as illustrated below.
Step 2: Next, continue to select the “Allow Calls From” option. In this step, if you don’t turn off the “Repeated Calls” option, numbers from outside your contacts will not be able to call you for the first time, but they can still call you for the second, third, etc. If you want to completely block calls from outside your contacts, simply turn off the “Repeated Calls” option. Note that you should consider carefully! Because once you turn it off, you will not receive calls from recruiters, relatives/friends who change their phone numbers, etc.
Step 3: To block calls from outside your contacts on iPhone, continue to select the “All Contacts” option. At this point, the iPhone system will understand that calls from numbers not saved in your contacts will be automatically blocked. You will only receive calls from phone numbers that have been saved in your contacts.
Step 4: Finally, simply turn on the “Do Not Disturb” feature on the control center.
Note: When using this method to block calls from outside your contacts, you need to consider it carefully. Because this method may affect your business, when old customers lose their old SIM cards and have to use another phone number to contact you, you will not receive their calls. Therefore, it is best to choose to block calls from specific unknown numbers.
