How to see whether the mobile phone number is mobile or Unicom?

If you use a Huawei mobile phone, some cards in the dual-card management interface do not display the phone number. You can check by the following methods:

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

2. 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.

3. 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.
