Can you find out the anonymous short messages sent by encryption software?

As long as the police make sure to check it, they can find it easily.

Because if you use a mobile phone to send text messages, the mobile phone has a phone number, and the phone numbers are all registered by real name. Check with the telecom operator and you will know who it is. If you send text messages on a computer, the network used by the computer has an IP address. If you know the IP address, you can find the user at once, and anonymous SMS can also find out where to send it at once, so it is easy to find the sender.

Short message is text or digital information sent or received directly 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.
