The text message reminded me that there was a call, but I couldn't see it.

The specific steps are as follows: 1. First, find the phone settings and enter the software settings. 2. Secondly, find the flash software in the software settings. 3. Finally, find the caller ID permission in the software and open it to display the caller ID.

SMS is a new short message service. When sending a flash message, the other party does not need to open it after receiving it, and the information content is directly displayed on the receiver's mobile phone screen. After reading, the information will not be saved automatically, and only a part can be saved manually. This service is only applicable to mobile users in China who send it to mobile users in China.
