There is a short message of 10086. I don't know what this means. Who can explain?

Every mobile phone has a service password.

Generally, you need a service password or ID card to modify the business in the business hall.

It seems that the initial business password is 666888, right?

But I'm not sure.

10086 informs you that your password is automatically set by the system and has not been modified, or you think your password needs to be modified.

If you can't remember the initial password, you can use your ID card to handle the service password.

In some cases, the service password can replace the ID card to handle some business.

So, it's still important,

There is nothing to worry about in this matter.
