How long can the public security organs check text message records?

Legal analysis: Usually within 6 months, the public security bureau can check the text messages, but they cannot check them casually. The freedom of communication and the confidentiality of communication of citizens of the People's Republic of China are protected by law. Except for the need for national security or the investigation of criminal crimes, where the public security organs or procuratorial organs inspect communications in accordance with the procedures prescribed by law, no organization or individual may infringe on citizens' freedom of communication and communication confidentiality for any reason.

Legal basis: "Criminal Procedure Law of the People's Republic of China" Article 148: After filing a case, the public security organs shall deal with crimes endangering national security, crimes of terrorist activities, and organized crimes of a mafia nature. For major drug crimes or other criminal cases that seriously endanger society, technical investigation measures may be taken after strict approval procedures based on the needs of investigating the crime. Technical reconnaissance measures include electronic interception, telephone monitoring, electronic surveillance, secret photography, video recording, mail checking and other secret specialized technical means. Naturally, SMS inquiries can also be carried out.
