Operator service password

This is easy to solve. First of all, you call the operator's customer service number, transfer to manual customer service, and tell the customer service that you need to know your mobile phone service password. Then the manual customer service will ask you to enter your real-name registration ID number, and the manual customer service will send you a service password after confirmation. You can change it into an easy-to-remember 6-digit password according to the received information. You don't need to modify it, as long as you can remember the service password sent to you by the customer service.
