I always receive a short message from a classmate's mobile phone. The imei serial number information is as follows: Keep this information by: so-and-so IMEI: IMEI: 35857003142 * * * * * *

This problem is easy to solve. Imei: Imei: 35857003142 * * * is the serial number of the mobile phone. The user of this mobile phone has turned on mobile phone tracking, and the number sent is your mobile phone. This classmate has an unusual relationship with you, right? His mobile phone was stolen or his mobile phone card or number was changed, which led to the mistake of his mobile phone being stolen. As long as he sends you or someone else a text message, he will always send you the above text messages, instead of saying that his mobile phone is poisoned. All you have to do is tell him to turn off cell phone tracking.
