How does Apple's mobile phone turn off spam filtering?

First click "Settings", enter "Information", and then turn off the top iMessage function. This function is very convenient for Apple users, because using iMessage to send messages between iPhone only requires traffic, while using SMS requires 0. 1 yuan.

Method 2: Turn on Filter Unknown Senders.

Click "Settings", enter "Information", and then turn on the "Filter Unknown Recipients" function, so that you won't receive spam messages outside the address book.

Method 3: Delete the email contact information.

Enter the "send and receive" information settings, delete the email contact information in iMessage contact information, and only keep the mobile phone number, because most spam messages are pushed by users' mailboxes.
