When someone calls, Huawei's mobile phone always shows unknown. How to set it?

If your mobile phone displays an "unknown" number when answering an incoming call, or displays an "unknown" number in the call record (as shown below), please troubleshoot according to the following scenarios:

1. All incoming calls are displayed as "unknown"

1. Please close "VoLTE HD Call" and restart your phone (some models don't have VoLTE HD Call).

It may be that the operator network is not normal. Please turn off the "VoLTE HD Call" switch, restart the phone, and check whether the caller ID is normal.

2. It is suggested that you clear the data of "dial" or "telephone".

Clearing the data and cache of "Dial" or "Phone" will not delete contacts and call records.

Method 1: Enter "Settings", search and enter "Application Management", and click the three-point icon? & gt show system processes > dial > store > delete data "(select the first dial);

Method 2: Enter "Settings", search and enter "Application Management", and click the three-point icon? & gt display system flow > telephone > storage > delete data "

Please insert your mobile phone card into other mobile phones with normal caller ID for testing.

If the incoming call still shows "Unknown", please contact the operator:

It is recommended that you contact the operator to confirm whether the caller ID function is enabled or consult the enabling method.

Maybe you didn't bring your number information when the network came in. I suggest you contact the operator to confirm the solution.

Second, the personal calling number is displayed as "unknown"

Unknown numbers may be displayed for the following reasons. If in doubt, please consult the operator.

1. Maybe the other party made the call with VoIP software.

2. Some mobile phones can set or use third-party software to block their own numbers and not send their own numbers.

3. The other party has handled relevant business in the operator department, so that the caller will not send his own number.

4. The other party called from abroad and sent the number to the calling party, but the information exchange between operators in different countries may be incompatible, which makes the number information lost in the transmission process and leads to the abnormal display of the incoming number.
