    iPhone does not provide the ability to block text messages from third-party services due to Apple's policy.

    Therefore, if you register as a blocking number in the WhoWho app, only the incoming call is blocked, and if you update the iPhone to iOS 11, you can use the 'spam message filtering' function provided by WhoWho.

    If you use this function, in addition to the numbers you have blocked, spam messages received from unknown numbers are automatically classified into 'junk' message boxes.

    Also, if you use advanced options, you can set the filtering conditions yourself, such as registering keywords, starting numbers, or setting image message filtering.

    Messages categorized as 'junk' mailboxes have the same effect as blocking, as arrival notifications are not triggered. (Similar to the email's spam mailbox)

    Spam Message Filtering' is a function that automatically classifies spam text messages into the 'Junk' message box (spam message box) of the iPhone message app through the app.

    Messages classified as the 'Junk' mailbox in the iPhone Messages app do not trigger a message arrival, so they can have the same effect as blocking (similar to a spam mailbox).

    The following messages are classified in the 'Junk' message box of the iPhone message app.
    1) The number that I blocked directly from the app
    -WhoWho App> 'More' tab> Number registered in 'Block Management' (except for numbers stored in contacts)
    2) The number of users who report spam
    3) Advanced filtering options set by the user
    ※ WhoWho App> 'More' tab> 'Message Filtering'> Advanced Filtering Options
    -Keyword filtering: Message containing the registered keyword
    -Filtering the starting number: the number starting with the registered number
    -Image message filtering: Message that receives only image files without text content

    The WhoWho app does not save the phone number and text content when checking whether the received text message is spam.

    It only checks whether the 'telephone number' of the received message is blocked or has a high probability of spam, and only tells iOS whether it is spam by comparing it with the keyword registered in advanced filtering.

    Apple provides a function to access text messages other than numbers, but the WhoWho only checks whether or not it contains a 'keyword', so you can rest assured about infringement of personal information.
