How to intercept strange text messages in iphone?

Apple's own system can't intercept it, so it can only block strange news without prompting. Taking Apple 1 1 as an example, there are the following steps:

1, open the settings in the phone.

2. Find the information option in the settings.

3. Click Information Filtering to find unknown and filtered information.

4. Just turn on the transmitter in the filtering position.

Precautions:

If a number keeps texting, you can click on the SMS sent by the contact you want to block, and click on Block, so that you can block any contact or number that has sent a text message.
