How does Apple 7P cancel the short message content displayed at the bottom of the call interface?

The currently used SIM card is installed on the iPhone.

Make sure the iPhone is connected to the cellular network.

Open the Settings app, and then click Info.

In the information panel, turn on the iMessage switch. When the other party also opens iMessage, the message sent is blue.

The method of displaying short message content when iPhone is locked;

1. Click General Center.

2. Enter the comprehensive center, select the reminder that needs to be set, and click Information, that is, SMS.

3. If all prompts are turned off and all switches are turned off, the screen lock reminder will be turned on, but the display on the screen lock needs to be turned off, that is, the specific content will be turned off.
