Can I receive the prison number if I write too many short messages?

SMS is a short message platform specially installed in prisons. Each prisoner has a code, which will be displayed on the electronic screen of the dormitory in the prison after receiving it. Print it out. The reply message must be approved by the police, and the sender of the message can help send it after agreeing. So as long as the code is good, the text messages sent by family members can be received, and of course they can be seen.
