Can mobile companies recover the text of short messages?

You can't see the message. All short messages are stored in code when passing through the repeater, and the system will encrypt each message (everyone's phone number is an identification number in the communication system and stored in binary), and the key is also binary, so the receiver's number is encrypted, so that the system will not send messages by mistake, which is impossible upstairs. If that's the case, the crime of being dumb has long since disappeared. And voice communication is online, and audio decoding is no longer a problem. When you think about the difficulty of text decoding, you can know that there are 26 characters in English alone, and the case is different. With punctuation, it takes a little time to decipher a password with 16 digits, not to mention Chinese with more than 50,000 basic characters. Who has time to decipher the mobile phone users in China?
