How does Apple's mobile phone intercept overseas calls?

The interception method is as follows:

First, open the settings icon, enter the settings, turn down the page, find "do not disturb mode" and open it directly.

2. At this time, the system defaults to the closed state of "do not disturb mode". Slide the switch button on the right to turn it on.

3. After opening the "Do Not Disturb" mode, click the "Allow the following calls" option at the bottom of the page.

4. At this time, if you want to prevent the harassment of all unknown and unfamiliar calls, then directly select all contacts here.

5. Then, on the Do Not Disturb Mode Settings page, select the Always option under Silent Mode.

6. In this way, no matter what happens when a strange phone calls in, it will prompt the reply tone of "the user is on the phone" or send a text message. No matter whether your iPhone screen is locked or bright, there will be no incoming call reminder interface, which is completely in silent mode, and only red numbers will be quietly displayed in the phone or information icon on the main screen, indicating that there are several missed or unread text messages.

Seven, as shown in the figure below, at this time, the phone call list shows when a strange phone call and how many times.

8. In the short message receiving list, we can also check the information sent by strange numbers. If you want to completely block strange numbers, click "Details" in the upper right corner.

9. In the page that opens, click the "More" button to the right of the strange number.

X. Select "Block this calling number" at the bottom of the page at this time.

XI。 A reminder menu option "You won't receive calls, messages or Facetime from blacklisted contacts" will pop up at the bottom of the page. If you are sure you want to permanently block this strange number, click Block Contacts.
