Apple set to intercept strange numbers and not intercept text messages.

Apple's method of setting up the interception of strange numbers without intercepting short messages is as follows:

Step 1: Open the iPhone and find the "Settings" icon. In the Settings option, locate the Notification sub-icon, and then click Enter.

Step 2: After entering the notification center, select "Information" in it. Locate "Show iMessage reminders for the following people" and select the "Show reminders in my address book" option.

Step 3: Add blacklist screening function to the new system, click Settings, select information and click blacklist. Select Add, and all your contacts will pop up automatically. Select the contact you want to block, and you will not receive calls, messages or FaceTime calls from the blacklisted contacts.
