Why can't Apple's mobile phone receive spam messages?

Take Apple 1 1 mobile phone and IOS 13.3 system as examples:

1. Call the operator's customer service phone and turn off the SMS function directly.

2. Turn on Apple's mobile phone, enter the "Settings" program, select the "Information" option, click "Send and Receive" after entering, and turn off the email address option.

If you just want to block a message, you can add it to the blacklist. Blacklists can be added to the address book. Click the "Add" function of the blacklist, check the contact, and click "OK". The number in the processing list can no longer be sent to your mobile phone.

If you want to set up the interception of harassing calls, you can open the main interface of the mobile phone, click the Settings application, slide down the interface to find and click the Do Not Disturb mode, click the option of "Allow the following calls" in the interface, check the option of "Favorite", and add the address book phone to enter the "Favorite".

(The above situations and methods are applicable to most mobile phone models of Apple. )
