Can a mobile phone that is no longer used as a police phone be used as an ordinary mobile phone?

No, the police service package is inherently difficult. Once transferred, it's gone, let alone transferred to another number. Just use the original number. Ordinary smart phones may leak police information and public security business content. According to the information released by mobile phone security experts in the industry, smart opportunities of some operating systems are used to automatically collect information such as user's name, location, wireless network signal strength near the location, and automatically send the information back to foreign headquarters. Imagine, if you know the police's name, frequent places and other information, how can the police's safety be guaranteed? How to keep the distribution information of national police force confidential? Especially how to protect the information of the police engaged in important police affairs? At the same time, ordinary smart phones may also cause the disclosure of police work business content. Because the access point is not the only one for ordinary smart phones, that is, the mobile phone can be used as both a police officer's card and an ordinary mobile phone. When using other access points, it may be invaded by some viruses or manipulation software, and these viruses may even invade the public security private network, posing a threat to the information disclosure of the public security private network.
