How can you know where a person is?

Take WeChat as an example, the way to find a person's location is as follows: Open your mobile phone and click WeChat APP. Find the friend whose location you want to see, and then click on the friend to send a message.

How to find out the location of the other party by phone: Generally, smart phones will know which city the other party is from when displaying the caller, so they can know the location of the caller as long as they look at the caller's reminder.

By sending and receiving signals to the satellite, the positioning should be on time. According to the signal interaction between the mobile phone and the mobile base station, you can see where you are, and do a CT for the other party, as long as it is set in the mobile phone setting options, because people control the mobile phone in other people's hands.

Contact by phone or text message: You can call or send a text message to ask about their recent situation, and you may get some useful information. Location by monitoring video or mobile phone: If the location function of the other party's mobile phone is turned on, you can track their location through mobile phone location.

All you can do is give him a call or ask his family, friends and colleagues. You can also ask a private detective for help, but there is a charge. If it is a special case, you can call the police.
