How to check the phone number of Huawei mobile phone?

If you use China Telecom's mobile phone card, China Telecom can only display the operator information, not the local phone number, and can't query the local phone number through the mobile phone. I suggest you call the operator's customer service hotline for consultation, or call other mobile phones to check the incoming number.

If you use the mobile phone card of China Mobile or China Unicom, you can check the phone number in Settings (> Wireless and Network) > Dual Card Management.

If the SIM card itself does not store the mobile phone number, it will display "Unknown" or not display the specific number. China Mobile SIM card is more common. I suggest you call the operator's customer service hotline for consultation.
