Brief introduction of Huawei mobile phone caller ID;

Let the other party cancel the hidden number service. You can tell the other party to cancel the hidden number service, so that when you make a call, the complete incoming number will be displayed on your mobile phone.

Change your phone settings. You can turn on your mobile phone, go to Settings, find "Call Display and Identification" in "Call", and then turn on this function, so that the real number of the other party will be displayed on your mobile phone when the call comes.

If the above two methods can't solve the problem, you can try to consult Huawei or operator customer service for more help.
