Caller ID is a very useful function. It can display the caller's phone terminal information on the mobile phone screen. The implementation of this function depends on the mobile operator, and different mobile operators have different technical implementation methods. Generally speaking, the caller ID will show the caller's number on the mobile phone, and will show the caller's city and country/region when needed. There are many ways to realize this function. Some operators will establish a connection with the server when an incoming call is made, and then send a query request to obtain the caller's dock information.However, some companies use front-end databases so that caller ID can be implemented in a slightly shorter time. No matter which implementation method is adopted, caller ID is very useful for preventing harassing calls and protecting user information. Why do you need a caller ID? Nowadays, more and more people use mobile phones as the main means of communication, and the number of harassing calls is also increasing. If you often receive strange calls, you may feel violated. However, if the city or country where the caller is located can be displayed on the mobile phone, this feeling will disappear. Caller ID can help us identify the caller more accurately.

If you can see the city or country of the caller, you can better judge whether the call is reliable or not. How to turn on the caller ID function of iPhone?
