How to intercept many authentication messages on Apple's mobile phone?

? Spam: Sometimes, we receive spam from emails instead of phone numbers. The reason why this happens is because the other party sends us spam messages through iMessage, not through the mobile phone number. Knowing this, we can block spam messages sent by iMessage with one click.

Turn off iMessage: Turn on Settings-Message and turn off iMessage (although iMessage can help us to send free messages, I believe everyone communicates through WeChat every day, so it is better to turn off iMessage instead of keeping iMessage).

? Enable system filtering: If you must use iMessage information, we can also enable filtering, setting-information, opening unknown information and filtering information in the iOS system, so that when we receive information from strangers, iOS will automatically help us put it into the "Filter Information" group.

Mobile users: If you are a mobile VoLTE user, you only need to send "ktfsr" or "Automatically intercept high-frequency numbers" to "10086" to enable the automatic interception of incoming calls with high-frequency numbers. (Free VoLTE needs to send "VoLTE" to "10086")

? Unicom users: send a text message "KT" to "10655587", and then Unicom will let us confirm it, and then send "y" to get it done.

? Telecom users? Since telecom has not provided us with a corresponding solution, we can only intercept the harassment through the software on the mobile phone. You can freely choose 360 mobile guards, Tencent mobile housekeeper, Baidu mobile guards and other interception tools to intercept harassment.
