Is 400 downloading SMS a fraud?

Don't trust the text messages monitored on the Internet and the text messages that can help you dig up N years ago. It's all liars. The user's SMS is peer-to-peer, but there is a record of sending and receiving in the telecommunications department. If they can't accept it (such as turning off the phone and logging off), they will temporarily put them in the "relay station" of SMS for a period of time [message center].

Only the sender and the receiver will have a short message record.

Android, ios and other smart phones can recover the deleted SMS records through certain methods (recovering the deleted SMS record files, and then recovering the SMS file contents through data recovery means), which is feasible. If it is not a smart machine, the recovery will be smaller. Of course, it is said that relevant departments can retrieve historical short message records. Oh, there is no reference to this.

North Asia Data Recovery Center has a program to help recover SMS records.
