What if Apple's mobile phone is bombed by SMS?

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).

Fraudulent calls and text messages: In fact, the operator official can provide us with the service of shielding harassing calls.
