How does Apple set up harassing calls to intercept sales phone text messages?

Because the numbers are changing, it is impossible to intercept and block incoming calls through the blacklist (block this incoming number). In this case, we can use the Do Not Disturb mode function of Apple's mobile phone to intercept and block such harassing calls that "call you to death".

Step 1: Enter Settings-Enable do not disturb mode.

Step 2: Set the time from 00: 00 to 23: 59, and the mute mode is always, allowing the next call to be all contacts.

The repeat call option is set according to the repeated number. Because the call number that "calls you to death" generally does not repeat, you can turn on the repeat call option, so that repeated calls can be connected within three minutes to avoid missing normal calls with strange numbers.

After the above operation, all strange numbers that are not in your Apple phone address book will be blocked. If it is a business call, there will often be express delivery or takeaway. This method is not applicable, but the courier and takeaway numbers can be connected by calling twice in a row.
