How to prohibit Apple's mobile phone from receiving information?

First of all, we should know that these spam messages are sent through iMessage, not the original SMS channel of operators. The imessage function can send data between iPhone, iPad, Mac and iPod through WIFI or cellular mobile as long as it is turned on in an iOS device.

How to shield it?

First of all, text messages are displayed separately.

You can set a separate page for strange messages in the settings. In this way, spam can be seen at a glance and will not be mixed in your daily text messages.

Open Settings → Information → Open the Filter Unknown Sender button.

Second, the report

You can report spam messages. There is a report button at the bottom of the unfamiliar iMessage message.

Third, if you don't want to watch it at all, you have to stop using the iMessage function.

Open Settings → Messages → Swipe right to close iMessage.

Hope to adopt. Good luck.
