Why does Xiaomi display group texting?

It's because text messages are sent in groups.

If the other party sends text messages in groups, it will show that all smartphones can send text messages in groups.

Group SMS mode: 1. Open contacts on your phone, and then click My Group.

2. Click on the group to send a message.

3. Click on "Group SMS".

4. Click the red box to select all, and then click OK.

5. Write a short message and click the arrow to send a short message. Mass SMS means that after you edit a short message, you send it in the form of mass email. So that all phone numbers stored in your phone can receive this message. Of course, you can also choose a few people to send in the group, or send them all.
