How to set emergency contacts not to view SMS?

In iOS 1 1 and newer systems, Apple has added the function of "SOS emergency contact" so that users can call for help through iPhone in case of emergency.

If necessary, you can do the following:

1. On iPhone 7 or earlier, quickly press the side (or top) button five times. The SOS Emergency Contacts slider will appear later.

2. On iPhone 8 or later models, press and hold the side button and any volume button until the "SOS Emergency Contact" slider appears.
