How do I block only incoming calls but not messages on my iPhone?

The reason why Apple phones only block incoming calls but not messages is because the function of intercepting text messages on Apple phones is not turned on. If you need to enable it, you can intercept messages. The specific process is as follows:

1. Taking Apple 6S as an example, find the "Settings" selected in the red box and click to proceed to the next step.

2. Enter the setting interface, find the "Information" option selected in the red box, and click to proceed to the next step.

3. In the information interface, find the "Unknown and Filtered Information" selected in the red box and click to proceed to the next step.

4. In the "Unknown and Filtered Information" interface, find the "Filter Unknown Senders" option selected in the red box and click to enter.

5. After clicking, the text message filtering function will automatically turn on.
