What is the reason why I suddenly can't receive the expected text message when I become an emergency contact?

The mobile phone is equipped with information interception function.

First, turn on the dial button in the mobile phone, click the three points in the upper right corner, click harassment interception, click interception rules, click telephone interception, find the interception function to be cancelled, and uncheck it.

The role of emergency contact is to be a backup contact or an auxiliary contact to help the company or school inform the family members of the parties. When one party has an accident, he can notify the emergency contact through the contact.
