Will spam messages be intercepted so as not to be discovered by the anti-fraud center?

If you don't intercept spam messages, you won't be found by the anti-fraud center. Even if SMS blocking is turned on, it is useless, because these messages are not sent by SMS, but by iMessage. IMessage is the function of sending and receiving messages through the network, which is somewhat similar to WeChat, but short messages are incorporated into the messages. When the other party enters your mobile phone number, Apple detects that you have turned on iMessage, and the information will be sent directly through the network, thus bypassing the interception of harassing text messages.
