Why can I still receive text messages from seven years ago?

The reason why the display time of the received SMS does not match the actual time may be the result of the other party's setting. Generally, these messages are sent by some illegal SMS operators.

You can contact your operator and call customer service to tell her the situation, and she will give you a reasonable solution. Short Message Service (SMS for short) refers to the text or digital information directly sent or received by users through mobile phones or other telecommunication terminals. The number of characters that users can send and receive SMS at a time is 160 English or numeric characters or 70 Chinese characters. On April 8, 2020, China Telecom, China Mobile and China Unicom jointly issued the White Paper on 5G SMS, which made the basic SMS service in China enter a comprehensive upgrade channel, and the traditional SMS will be gradually replaced by 5G SMS (RCS service).
