How does q3pro Carnival Edition check the mobile phone card number?

You can call someone directly with your mobile phone, and then you can know your phone number by looking at the number displayed on the other person's mobile phone.

You can also find "Settings" on the mobile phone desktop, then click "Settings" to enter the setting interface, find "Dual Card Management" and click "Dual Card Management" to display the mobile phone number of this machine;

Or you can click "Settings" to enter the setting interface, where you can find "About Mobile Phone", then click "About Mobile Phone" to enter the next interface, find "Status Information", enter the status information interface, find the bottom "SIM Card Status", and click "SIM Card Status" to find the phone number of this machine;

You can view the phone number by directly entering the command indicator in the phone. The premise is that Android phones can query like this. Enter the command: * # * # 4636 # * # in the telephone interface, and you can see your mobile phone number.

If the above methods can't help users to check their mobile phone numbers, they need to bring their ID cards to the relevant business halls for consultation.
