What does it mean for the police to collect information from my mobile phone?

According to the relevant regulations regulating information collection, the information collected by public security organs should meet the needs of normal police work and will not affect their future work and life.

In addition, Chapter VI, Article 77, Paragraph 4 of the National Security Law stipulates:

Citizens and organizations shall provide convenience or other assistance for national security work. Article 83 When national security requires special measures to restrict citizens' rights and freedoms, they shall be taken in accordance with the law and shall be limited to the actual needs of safeguarding national security.

There is a legal basis for the bureau to collect citizen's mobile phone card information, and we should cooperate with it.

However, if it is based on the needs of national security, unreasonable demands such as obvious violation of personal privacy can also be rejected.
