Can a police phone be connected to an external computer?

The police mobile phone is mainly used for the internal transmission of some pictures and information of police officers, which is mainly a system network within the police. So, as you said, it is impossible for a laptop to surf the Internet through mobile phones and mobile phone traffic.

Regarding your first question, when I disconnect my laptop, can I use activesync software to connect my mobile phone? It is only used to transfer pictures or documents between my computer and my mobile phone. Personally, I think it should be possible.
