What does it mean to have a bell with a diagonal line after the name of the mobile phone WeChat group? You can't send a message, but the message will be followed by a red exclamation point.

A bell with diagonal lines means don't disturb. When this function is turned on, there will be no message prompt. The red exclamation mark indicates that the network is not smooth and the information transmission is unsuccessful.

You can cancel the Do Not Disturb setting by following these steps:

1. First open the "WeChat" icon on the mobile phone desktop, as shown in the figure below.

2. Secondly, select a group and enter the group chat interface, as shown in the figure below.

3. Then, click on the three points in the upper right corner of the group chat interface, as shown in the figure below.

4. Then, turn off the switch behind the "Do Not Disturb" option, as shown in the figure below.

5. Finally, when the switch is turned off, it will turn gray, so as to prompt when there are other messages, as shown in the figure below.
