What should I do if I forget my mobile phone pin?

Every mobile phone calling card has a PIN code. When you just buy a mobile phone card, you usually have two initial passwords. You can modify the PIN code. If you forget the revised password, your mobile phone may be locked and you can't receive text messages or phone calls. The following is a solution demonstration using the device model: ZUK Z 1 and the mobile phone system version: ZUI 2.3.055:

1. Enter the setting interface, and be careful when entering the PIN code of the SIM card. If you make more than three mistakes, the mobile phone card will be automatically locked.

2. At this time, we need to log in to China Mobile Pocket Business Hall, enter our account number and password, and click the customer service icon in the upper right corner.

3. Enter the chat interface with customer service, enter the forgotten pin code in the input box, carefully read the information sent by the other party, and click at the bottom to see more.

4. The interface jumps, and we read the content carefully to find the correct solution.

5. Enter 10086 in the dial-up interface of mobile phone, call the official customer service of China Mobile, inform the correct ID number and mobile phone number, and modify the pin code.

Precautions:

1. If you can't use the above, you can go to China Mobile Business Office with your mobile phone and ID card, and ask customer service to help you modify your PIN code.

2. Be careful when entering the PIN code of the SIM card. If you enter it incorrectly for more than three times, the mobile phone card will automatically lock.
