Extended data:

Service password is the identification password of mobile, China Unicom and telecom customers, which consists of a set of 6 digits (each digit can be any number between 0 and 9).

When using this number for the first time, mobile phone users should remember to set the service password in person. If they have a service password, they should modify it immediately, and modify the service password 1 time at least within one month after purchasing a set of cards or newly accessing the network to ensure the confidentiality of the password. Also remember not to set an overly simple service password.

At present, operators have strict anti-theft measures for service passwords, and users have SMS notifications when logging in to online business halls and handling business at physical outlets.
